Аннотация: Various manifestations of the exchange interaction effects in magnetization curves of the CoPt nanostructured particles are demonstrated and discussed. The inter-grain exchange constant A in the sponge-like agglomerates of crystallites is estimated as A=(7±1) pJ/m from the approach magnetization to saturation curves that is in good agreement with A=(6.6±0.5) pJ/m obtained from Bloch T 3/2 law. The fractal dimensionality of the exchange coupled crystallite system in the porous media of the disordered CoPt alloy d=(2.60±0.18) was estimated from the approach magnetization to saturation curve. Coercive force decreases with temperature as Hc~T 3/2 which is assumed to be a consequence of the magnetic anisotropy energy reduction due to the thermal spin wave excitations in the investigated CoPt particles. © 2015 Elsevier B.V.

Демонстрируются и обсуждаются различные проявления эффектов обменного взаимодействия в кривых намагниченности наноструктуированных частиц CoPt. Межзеренная обменная константа А в агломератах губчатой структуры кристаллитов оценивается как /A/=(7±1) pJ/m из кривых приближения намагниченности к насыщению, это значение находится в хорошем согласии с /A/=(6.6±0.5) pJ/m, полученным из закона /T/. /2 Блоха. Размерность фрактала обменно-соединенных кристаллических систем в пористой среды неупорядоченного сплава CoPt /d/=(2.60±0.18) оценивалась из кривых приближения намагниченности к насыщению. Коэрцитивная сила уменьшается с температурой по закону /H_c /~/T/. /2 , который, как предполагается, есть следствие уменьшения энергии магнитной анизотропии из-за теплового возбуждения спиновых волн в изучаемых частицах CoPt.

The direct exchange mechanism of induced spin polarization of low-dimensional π-conjugated carbon- and h-BN fragments at LSMO(001) MnO-terminated interfaces / A. V. Kuklin [et al.] // J. Magn. Magn.

Graphene nanoribbons -- DFT -- LSMO thin films -- Induced spin polarization -- h-BN nanoribbons -- Half-metal
Аннотация: Induced spin polarization of π-conjugated carbon and h-BN low dimensional fragments at the interfaces formed by deposition of pentacene molecule and narrow zigzag graphene and h-BN nanoribbons on MnO2-terminated LSMO(001) thin film was studied using GGA PBE+U PAW D3-corrected approach. Induced spin polarization of π-conjugated low-dimensional fragments is caused by direct exchange with Mn ions of LSMO(001) MnO-derived surface. Due to direct exchange, the pentacene molecule changes its diamagnetic narrow-band gap semiconducting nature to the ferromagnetic semiconducting state with 0.15 eV energy shift between spin-up and spin-down valence bands and total magnetic moment of 0.11 μB. Direct exchange converts graphene nanoribbon to 100% spin-polarized half-metal with large amplitude of spin-up electronic density at the Fermi level. The direct exchange narrows the h-BN nanoribbon band gap from 4.04 to 1.72 eV in spin-up channel and converts the h-BN ribbon semiconducting diamagnetic nature to a semiconducting magnetic one. The electronic structure calculations demonstrate a possibility to control the spin properties of low-dimensional π-conjugated carbon and h-BN fragments by direct exchange with MnO-derived LSMO(001) surface for spin-related applications.

Аннотация: The specific heat, thermal expansion, permittivity, and electrocaloric effect in bulk of BaTiO3 (BT) samples in the form of nano- (nBT-500 nm) and micro- (mBT-1200 nm) ceramics fabricated using spark plasma sintering and solid-state plasma techniques have been investigated. The size effect has been reflected, to a great extent, in the suppression of the specific heat and thermal expansion anomalies and in the changes in the temperatures and entropies of phase transitions and permittivity, and a decrease in the maximum intensive electrocaloric effect: ΔTmaxAD = 29 mK (E = 2.0 kV/cm) for nBT and ΔTmaxAD = 70 mK (E = 2.5 kV/cm) for mBT. The conductivity growth at temperatures above 360 K leads to the significant irreversible heating of the samples due to the Joule heat release in the applied electric field, which dominates over the electrocaloric effect.

Аннотация: Atomic and electronic structures of Goldberg-type silicon quantum dots and their endohedral erbium complexes were studied using ab initio and plane wave pseudopotential density functional and Moller-Plesset many-body perturbation theories. During atomic structure optimizations, the erbium ions occupy mass centers inside the central hollows of quantum dots of different symmetries. It was found that strong electron correlations within the Er 4f shell taken into account by empirical pseudopotential and post-Hartree-Fock perturbation approaches are responsible for strong binding of Er ions to quantum dots. We elucidate the effects of symmetry and discuss theoretical results in comparison to available experimental data,

Аннотация: The solid-state synthesis of magnetically soft phase FePd3 in epitaxial Pd(0 0 1)/Fe(0 0 1)/MgO(0 0 1) film systems was studied experimentally. The system had a Fe to Pd ratio of 1:3. An increase to 450 °C leads to the formation of three variants of ordered L10-FePd crystallites. At 500 °C, the solid-state reaction of unreacted Pd with L10-FePd crystallites initiates the growth of an ordered epitaxial L12-FePd3(0 0 1) layer. When annealing at 650 °С, a gradual disordering is observed. The magnetic anisotropy (K1=−2.0×103 erg/cm3) and the saturation magnetization (MS=650 emu/cm3) of the disordered FePd3 phase were determined.

Аннотация: Solid-phase synthesis of solid solutions in the epitaxial Cu/Ni(001) bilayer film systems of compositions 3Cu: 1Ni, 1Cu: 1Ni, and 1Cu: 3Ni has been studied using the X-ray diffraction methods. The saturation magnetization and the magnetic crystallographic anisotropy constant on nickel vary in accordance with the solid solution formation. The initiation temperature of the solid solutions is about 350 A degrees C and is independent of the Ni: Cu layer thickness ratio. The solid-phase synthesis of the solid solutions is presumably attributed to the transport of the Cu atoms to the epitaxial Ni(001) layer. It is found that the solid-phase synthesis in the Cu/Ni bilayer nanofilms and multilayers is determined by the spinodal decomposition in the Cu-Ni system.

Аннотация: The solid-phase synthesis of the Co(7)Sm(2) and Co(17)Sm(2) magnetically hard phases in Co/Sm/Co(110) epitaxial film systems has been experimentally investigated. The Co(7)Sm(2) phase is first formed at the Sm/Co interface at a relatively low (similar to 300 degrees C) temperature. As the annealing temperature increases to similar to 450 degrees C, the Co(17)Sm(2)(110) phase grows epitaxially on the Co(7)Sm(2)(110) phase. The saturation magnetization and biaxial anisotropy constant in the samples vary with the formation of the Co(7)Sm(2) and Co(17)Sm(2) phases. Investigations of the solidphase synthesis in the nanofilms reveal the existence of a new structure phase transition at 300 degrees C in the Co-Sm system with a high cobalt content.

Аннотация: Solid-phase reactions taking place in Al/beta-Co/MgO(001) and Al/alpha-Co/MgO(001) film systems under conditions of self-propagating high-temperature synthesis (SHS) are investigated. In both systems, SHS products exhibit the single CoAl superstructure, which epitaxially grows on the MgO(001) surface in the Al/beta-Co/MgO(001) structures and has a fine-dispersed disordered structure in the Al/alpha-Co/MgO(001) films. It appears that the difference in the reagent structure has an effect on the energy of activation but does not change the SHS initiation temperature and the temperature at which the initial phase involved in the reaction products nucleates. It is shown that the SHS initiation temperature in the Al/beta-Co/MgO(001) and Al/alpha-Co/MgO(001) systems coincides with the temperature of CoAl superstructure ordering.

Аннотация: The classical solid-phase reaction between Fe2O3 and Al layers in thin films is initiated. It is shown that, in the reaction products, Fe granulated films are formed in the Al2O3 nonconducting matrix. Analysis of the reaction equation demonstrates that the volume fraction of iron in the granulated films is less than the percolation threshold. This determines the magnetic properties of iron clusters in a superparamagnetic state. It is assumed that the nanocrystalline microstructure exists in thin films after solid-phase reactions proceeding under conditions of self-propagating high-temperature synthesis.

Аннотация: It is shown that annealing 550°C of the Fe/Pt bilayer films fabricated by layer-by-layer deposition onto polycrystalline Al2O3 substrates in an atomic ratio of Fe: Pt = 71: 29 leads to the formation of the inplane rotational magnetic anisotropy with the easy axis that can be aligned by magnetic field in any direction in the film plane. The increase in the Pt content in the investigated film system to 50 at % leads to an increase in the anisotropy constant to 6.5 × 106 erg/cm3, which exceeds the value in the Fe71Pt29 sample by a factor of 6. In addition to the rotational anisotropy, the Fe50Pt50 films are characterized by the perpendicular rotational magnetic anisotropy, which is higher than the film shape anisotropy. Therefore, the easy axis in these samples can be aligned by magnetic field in any spatial direction. According to the X-ray and magnetic measurement data, the synthesized samples have a polycrystalline structure consisting of two ordered phases: magnetically hard L10–FePt and magnetically soft L12–Fe3Pt. This gives us grounds to suggest that the rotational magnetic anisotropy originates from the epitaxial intergrowth and exchange coupling of these two phases.

Possibility of a 2D SiC monolayer formation on Mg(0001) and MgO(111) substrates / A. A. Kuzubov [et al.] // Russ. J. Phys. Chem. A. - 2013. - Vol. 87, Is. 8. - P. 1332-1335, DOI 10.1134/S0036024413080141. - Cited References: 25 . - ISSN 0036-0244

Аннотация: The geometrical characteristics of a 2D SiC monolayer on Mg(0001) and MgO(111) plates regarded as potential materials for growing two-dimensional silicon carbide were studied. The most favorable positions of the atoms of 2D SiC on the substrates were determined. In the 2D SiC/Mg(0001) system, unlike in 2D SiC/MgO(111), the deviation of the carbon atom from the silicon carbide monolayer was insignificant (0.08 ). Consequently, magnesium can be used as a substrate for growing two-dimensional silicon carbide. The use of MgO(111) is not recommended because of a significant distortion of the 2D SiC surface.

Аннотация: Results of an X-ray diffraction study as well as magnetic and electrical measurements of the solid-state reactions in Ge/Mn polycrystalline films of an 80/20 atomic composition have been presented. It has been shown that the ferromagnetic Mn5Ge3 phase is formed first on the Ge/Mn interface after annealing at similar to 120A degrees C. The further increase in the annealing temperature to 300A degrees C leads to the beginning of the synthesis of the Mn11Ge8 phase, which becomes dominating at 400A degrees C. The existence of new structural transitions in the Mn-Ge system in the region of similar to 120 and similar to 300A degrees C has been predicted on the basis of the presented results and results obtained earlier when studying solid-state reactions in different film structures. The supposition about the general chemical mechanisms of the synthesis of the Mn5Ge3 and Mn11Ge8 phases during the solid-state reactions in the Ge/Mn films of the 80/20 atomic composition and the phase separation in Ge (x) Mn1 - x (x 0.95) diluted semiconductors has been substantiated.

Аннотация: The solid-phase synthesis in epitaxial Mn/Fe(001) bilayer film systems with 24 at % of Mn has been shown to start at a temperature of 220A degrees C with the formation of a gamma-austenite lattice and the Mn and Fe films react completely under annealing to 600A degrees C. In the sample cooling process after annealing below 220A degrees C, the gamma austenite undergoes a martensitic transformation to an oriented a(100) martensite. When the annealing temperature is increased above 600A degrees C, Mn atoms migrate from the gamma-lattice, which becomes unstable, and the film is partially again transformed to the epitaxial Fe(001) layer. The solid-phase synthesis in Mn/Fe(001) bilayer nanofilms and multilayers is assumingly determined by the inverse epsilon - gamma martensitic transformation in the Mn-Fe system. The existence of a new low-temperature (similar to 220A degrees C) structure transition in the Mn-Fe system with a high iron content is assumed.

Аннотация: A methods of obtaining polycrystalline CoCrFeO4 films based on solid-phase reactions in Cr2O3/Co/Fe layer structures in the regimes of isothermal annealing and self-propagating high-temperature synthesis (SHS) is described. The magneto-optical properties of the obtained films have been studied. It is established that the spectra of magneto-optical characteristics depend on the solid-phase reaction regime and synthesis temperature. The Faraday rotation angle exhibits a local maximum (2 theta(F) = 5 deg/mu m) at a wave-length of 630 nm.

Аннотация: This paper is devoted to the development of reflection magneto-optical ellipsometry. We have solved the inverse problem for structures with uniaxial optical anisotropy: have determined the reflection coefficients for the ambient-sample interface, and have derived an analytic expression for magneto-optical parameter Q proportional to the magnetization. This expression makes it possible to determine parameter Q exclusively from experimental data obtained using magneto-optical ellipsometry. We present a detailed algorithm for performing experiment on determining the dielectric tensor in the transverse geometry.

Аннотация: We report on the low-temperature magnetic properties of the DyScO3 perovskite, which were characterized by means of single crystal and powder neutron scattering, and by magnetization measurements. Below TN = 3.15 K, Dy3+ moments form an antiferromagnetic structure with an easy axis of magnetization lying in the ab plane. The magnetic moments are inclined at an angle of ∼ +/- 28 degrees to the b axis. We show that the ground-state Kramers doublet of Dy3+ is made up of primarily |+/- 15/2 ⟩ eigenvectors and well separated by a crystal field from the first excited state at E1 = 24.9 meV. This leads to an extreme Ising single-ion anisotropy, M⊥/M∥∼ 0.05. The transverse magnetic fluctuations, which are proportional to M⊥2/M∥2, are suppressed, and only moment fluctuations along the local Ising direction are allowed. We also found that the Dy-Dy dipolar interactions along the crystallographic c axis are two to four times larger than in-plane interactions.

Аннотация: Macroscopic and local magnetic anisotropy of [CoFeB-SiO2/α-Si:H]60 multilayer films was studied in comparison with that for the thick CoFeB-SiO2 granular films. The volume fraction of magnetic component Co40Fe40B20 is ranged from 0.34 to 0.70. In the multilayer films the magnetic layer and silicon spacer thicknesses are 2.5÷4.5 nm and 3.5 nm correspondingly. The magnetization curves and ferromagnetic resonance measurements were used to determining magnetic anisotropy energy constants. The main contribution to the local magnetic anisotropy energy constant is found to be from surface magnetic anisotropy of magnetic granules. It is found that the magnetic percolation point of multilayer films (XC~40) is shifted in comparison with that in granular films (XC~30). Surface magnetic anisotropy energy constants of multilayer films with different X evaluated from the surface modes of spin-wave resonance are in the range 0.5 Ks 0.9 erg/cm2.

Аннотация: The structural and magnetic properties of CoPt-In2O3 nanocomposite films formed by vacuum annealing of the In/(Co3O4 + Pt)/MgO film system in the temperature range of 100–800 °C have been investigated. The synthesized nanocomposite films contain ferromagnetic CoPt grains with an average size of 5nm enclosed in an In2O3 matrix, and have a magnetization of 600 emu/cm3, and a coercivity of 150 Oe at room temperature. The initiation 200 °C and finishing 800 °C temperatures of synthesis were determined, as well as the change in the phase composition of the In/(Co3O4 + Pt)/MgO film during vacuum annealing.
Исследованы структурные и магнитные свойства нанокомпозитных пленок CoPt- In2O3, полученных вакуумным отжигом пленочной системы In/(Co3O4 + Pt)/MgO в интервале температур 100 – 800 °C. Синтезированные нанокомпозитные пленки содержали ферромагнитные CoPt-кластеры со средним размером 5 nm, заключенные в матрицу In2O3, и имели намагниченность 600 emu/cm3, коэрцитивную силу 150 Oe при комнатной температуре. Определены температуры начала 200 °C и окончания 800 °C синтеза, а также изменение фазового состава пленки In/(Co3O4 + Pt)/MgO при вакуумном отжиге.
