Аннотация: The processes of phase formation during a solid-state reaction between Fe and Al nanolayers have been investigated by the in situ electron diffraction method. It is established that the solid-state reaction at the interface between iron and aluminum nanolayers begins at ≈100°C with the formation of a disordered Al solid solution in α-Fe. It is shown that intermetallic phases (FeAl6 and/or Fe2Al5, FeAl, and Fe3Al) are successively formed upon further heating.

Аннотация: This paper reports studies of thin films of nickel oxide obtained by the extraction–pyrolysis method on glass and quartz substrates at temperatures of 380–600°C. The films have been characterized by atomic force microscopy and X-ray diffraction. It is shown that amorphous and crystalline nickel oxide films are formed on the glass. The grain size depends on the annealing temperature, while increased annealing temperatures lead to recrystallization and a decrease in the grain size in NiO films from 130 to 35 nm.

Аннотация: The structural and magnetic properties of a niobium nitride (NbN) film prepared by reactive sputtering onto a quartz substrate are investigated. It is shown using scanning electron microscopy that the film has a columnar structure with a diameter of crystallite columns of about 50 nm. The film magnetization loops are measured for the field orientation parallel and perpendicular to its surface. Based on the experimental data, the critical current densities of the film are estimated in both cases. For the field parallel to the film surface, the estimate is 6.5 × 104 A/cm2 at the liquid helium temperature. For the field perpendicular to the surface, the critical current density is close to the depairing current density (107 A/cm2). Analysis of the results based on different models of magnetic vortex pinning in superconductors shows that in the former case, pinning occurs at the boundaries of columns in the bulk of the sample, while in the latter case, it is determined by the influence of the surface barrier.

Аннотация: The paper presents the results of the formation and study of the morphological and structural characteristics of the mesoporous ZnO / Al2O3 nanofibers film (ZANF). The deposition of a ZnO layer on Al2O3 nanofibers film (ANF) ~ 1 µm thick was carried out by the method of atomic layer deposition. The morphology of the mesoporous composite layer ZnO / Al2O3 (ZANF) has been studied by scanning and transmission electron microscopy. It is shown that in the process of atomic layer deposition, the ZnO layer grows according to the Stranski-Krastanov mechanism. A ZnO layer less than 5 nm thick gives an island structure in which Al2O3 nanofibers are uniformly coated with ZnO particles, an increase in the ZnO layer thickness to 15 nm demonstrates a continuous coating of Al2O3 nanofibers. The system has a core-shell structure. The resulting composite structures are promising for applications in photocatalysis and gas sensing.

Аннотация: We have analyzed chemical bonding of atmospheric oxygen with chromium and manganese on the epitaxial MAX-phase (Cr0.5Mn0.5)2GaC surface using Auger electron spectroscopy combined with ion etching. It was found that the system has a specific anisotropic oxidation where oxygen atoms bind to chromium and manganese ones more actively at the faces of layered MAX phase crystallites in contrast to the (0001) basal plane. At the same time, the dominance of the Mn–O chemical bonding over Cr–O is observed on the latter.

Аннотация: This paper considers hardware and software for automated analysis of thin magnetic film ferroresonance spectrum to determine the rate of growth and decrease in ferroresonance spectrum (conversion factor parameter). The measuring element of automated system is the strip line which is short-circuited. The measuring unit is used to study Ni 80 Fe 20 permalloy films, with thickness of more than 300 Å. Conversion factor, magnetic permeability μ, uniaxial magnetic anisotropy, ferromagnetic spectrum resonance line width, saturation magnetization are analyzed from 50 MHz to 2 GHz frequency range. The magnetic films are used to design frequency selective filters, phase shifters and weak-field magnetic sensors. The thin magnetic film sensors are high sensitive magnetometers, with wide frequency range, low dimensions and weight [1]. © 2019 IEEE.

Аннотация: The relation between the effective ordinary refractive index n* = (n o n e )1/2 of a quasi-two-dimensional polydomain uniaxial film of a conjugated polymer F8BT in the visible transparency region and the refractive indices (n o,e ) of uniaxial domains with the optical axes randomly oriented in the plane of the film has been confirmed experimentally. The permissible interval of variations in n* has been established and a strong spectral dispersion of this interval near the long-wavelength electronic absorption band of the film has been demonstrated.

Аннотация: The dimension D of a polycrystalline film and the optical anisotropy m = εz/εx of uniaxial crystallites with the principal components εx = εy and εz of the tensor of the dielectric constant have been shown to produce a strong influence on the effective dielectric constant εD* and the effective refractive index nD* = (εD*)1/2 of the film in the optical transparency region, as well as on the boundaries of the intervals BDl ≤ εD* ≤ BDu. The intervals Δ2(m) = B2l–B2u and Δ3(m) = B3l–B3u are separated by a gap for m in the range 1 m 2, whereas the theoretical dependence ε2*(m) is separated by a gap from the interval Δ3(m) for m in the range 1 m 4. This is confirmed by a comparison of the experimental (noP) and theoretical (nD*) ordinary refractive indices for uniaxial polycrystalline films of the conjugated polymer poly(p-phenylene vinylene) (PPV) with uniaxial crystallites and appropriate values of m. In the visible transparency region of the PPV films with a change in m(λ) in the range 2 m(λ) 3 due to the dependence of the components εx,z(λ) on the light wavelength λ, the refractive indices noP2(λ) 3 near the electronic absorption band of the crystallites, the values of εoP(λ) lie in the region of the overlap of the intervals Δ2(m) and Δ3(m). The boundaries mc of the range 1 m mc are determined, for which the interval Δ2(m) is separated by a gap from the dependences ε3*(m) corresponding to the effective medium theory with spherical crystallites and hierarchical models of a polycrystal, as well as from the proposed new dependence ε3*(m).

Заглавие : Anisotropy characteristics in a Permalloy film induced by a nonuniform magnetic field
Место публикации : Phys. Solid State: AMER INST PHYSICS, 1998. - Vol. 40, Is. 7. - P1175-1177. - ISSN 1063-7834, DOI 10.1134/1.1130513

Аннотация: Inhomogeneities were observed for the first time in the magnetic structure of a thin Permalloy film, induced by a strongly nonuniform magnetic field applied in the plane of the substrate during fabrication of the samples. The films were obtained by vacuum deposition using a molecular-beam epitaxy system. A nonuniform field was created on the substrate using four samarium-cobalt magnets. The anisotropy of local sections of the samples was measured using a scanning-ferromagnetic-resonance spectrometer. A strong correlation was observed between the distribution of the magnitude and direction of the local magnetic anisotropy of the film and the magnetic-field distribution in the plane of the substrate.

Ключевые слова (''Своб.индексиров.''): thin film--magnetic anisotropy--oblique deposition--ferromagnetic resonance--micromagnetic simulation
Аннотация: Distribution of the magnetic anisotropy in thin film prepared by thermal vacuum oblique deposition of permalloy with small off-normal angle of incident in the presence of an external magnetic field has been studied by ferromagnetic resonance technique. On local area of the sample, a mutual compensation of near orthogonal in-plane uniaxial magnetic anisotropies induced by oblique deposition and by applied magnetic field has been found. Moreover, in addition to the uniaxial (twofold) magnetic anisotropy, fourfold and sixfold magnetic anisotropies have been observed in the sample. To explain the obtained high-order anisotropies, we assumed that the sample has exchange coupled adjacent regions or phases with different parameters of magnetic anisotropy. The results of the micromagnetic analysis of a two-layer model of the sample confirm the hypothesis. © 2015 Elsevier B.V. All rights reserved.

Аннотация: The anisotropic characteristics of an iron silicide (Fe3Si) epitaxial thin magnetic film grown on a Si(111) silicon vicinal surface with a misorientation angle of 0.14° have been measured by the ferromagnetic resonance method. It has been shown that the polar and azimuth misorientation angles of the crystallographic plane of the substrate can be determined simultaneously from the angular dependences of the ferromagnetic resonance field of the epitaxial film. The effective saturation magnetization of the film M eff = 1105 G and the constant of the cubic magnetocrystalline anisotropy K 4 = 1.15 × 105 erg/cm3 have been determined. The misorientation of the substrate plane leads to the formation of steps on the film surface and, as a result, to the appearance of uniaxial magnetic anisotropy of the magnetic dipole nature with the constant K 2 = 796 erg/cm3. Small unidirectional magnetic anisotropy (K 1 = 163 erg/cm3), which may be associated with symmetry breaking on the steps of the film and is due to the Dzyaloshinskii–Moriya interaction, has been detected.

Ключевые слова (''Своб.индексиров.''): oblique angle deposition--simulation of film growth--monte carlo method
Аннотация: Based on the Monte Carlo method, a model of growth of thin films prepared by oblique angle deposition of particles is constructed. The morphology of structures synthesized by simulation is analyzed. To study the character of distribution of microstructural elements (columns) in the film plane, the autocorrelation function of the microstructure and the fast Fourier transform are used. It is shown that with increasing angle of particle incidence, the film density monotonically decreases; in this case, anisotropy arises and monotonically increases in the cross sections of columns, and the anisotropy of distribution of columns in the substrate plane also increases.

Аннотация: The magnetic structure of thin nanocrystalline films with a random distribution of magnetization easy axes was studied by means of micromagnetic modeling. The dependences of the correlation function parameters of the non-uniform magnetization on the value of the external in-plane magnetic field were investigated in the wide range (6–1000 nm) of particles sizes. An analysis of the obtained dependences revealed a significant difference between longitudinal (along the field) and transversal (perpendicular to the field) correlation radii of a stochastic magnetic structure. The blocking effect of a fine magnetic structure—a magnetization ripple—was observed during magnetization reversal of the films. © Siberian Federal University.

В широком диапазоне размеров частиц 6 1000 нм исследованы зависимости параметров корреляционной функции неоднородной намагниченности от величины внешнего планарного магнитного поля. Анализ полученных зависимостей показал существенное различие корреляционных радиусов стохастической магнитной структуры вдоль и поперек направления приложенного поля. При перемагничивании тонких пленок наблюдался эффект блокировки тонкой магнитной структуры "ряби намагниченности".

Аннотация: The original Co(001)/Pt(111) film structure has been obtained by consequent thermal deposition of Co layer with a cubic crystal lattice and Pt(111) from the target sprayed using a magnetron sputtering technique on a single crystal substrate of MgO(001) in the vacuum of 10 -6 Torr. In the experiments we have used thesamples with the atomic ratio: 1Сo:3Pt and1Сo:1Pt; totalthickness is about300 nm. The X-ray diffraction analysis has shown that in two-layer structures with the atomic ratio of reagents 1/3, at temperatures of annealing T = 500 and 850 ?С in the interlayer chemical interaction, phases of epitaxial cubic compounds CoPt 3 (L1 2 ) are formed. The annealingof the samestructures with1/1 ratio leads to the formationof the second phaseCoPt(L1 0 )withtetragonal distortion. The newly formedL1 0 CoPtphasegrowsepitaxiallyon the base of the pre-synthesized L1 2 CoPt 3 phasewith the sameorientation relationship. The peculiarity of the films withatomic ratio Co / Pt = 1/1at T =850°Cis the presence of“perpendicular” anisotropy due tothe exchange interactionof twoformed ordered phasesCoPt (111) and CoPt 3 (111).Исходные плёночные структуры получены последовательным термическим осаждением слоя Со с кубической кристаллической решеткой и Pt(111) из мишени, распыляемой с использованием методики магнетронного распыления на монокристаллическую подложку MgO(001) в вакууме 10 -6 торр. В экспериментах использовались образцы с 1Со:3Pt и 1Со:1Pt атомным отношением общей толщиной порядка 300 нм. Рентгеноструктурные исследования показали, что в двухслойных структурах с атомным соотношением реагентов 1/3, при температурах отжига при Т = 500 и 850 о С в результате межслойного химического взаимодействия формируются фазы эпитаксиального кубического соединения CoPt 3 (L1 2 ). Отжиги этих же структур с соотношением 1/1 приводят к формированию второй фазы СoPt (L1 0 ) с тетрагональным искажением. Вновь сформированная L1 0 CoPt фаза растет эпитаксиально на базе предварительно синтезированной L1 2 CoPt 3 фазе с тем же ориентационном соотношением. Особенностями пленки с атомным соотношением Co/Pt = 1/1 при Т = 850 о С является наличие «перпендикулярной» анизотропии, обусловленной обменным взаимодействием двух сформированных упорядоченных фаз CoPt(111) и CoPt 3 (111).

Аннотация: The paper presents a method for measuring the ferromagnetic resonance spectrum in the radio frequency range (4 MHz). A high-frequency generator operating in the autodyne mode was used to measure the magnetic characteristics of thin ferromagnetic films. Theoretical equations for ferromagnetic resonance excitations have been presented. Experimental results for the samples of nanocrystalline thin permalloy magnetic films with low magnetostriction and different values of the anisotropy field were obtained. Ferromagnetic resonance in the radio frequency range proved to be an excellent mean for measuring the value and direction of the magnetic anisotropy field in thin magnetic films.
