Аннотация:
Planar and vertical hybrid structures, which combine ferromagnetic and semiconductor layers are essential for implementation and study of spin transport phenomena in semiconductors, which is crucial for the advancement and development of spintronics. We have developed approaches for the synthesis of Fe3 + xSi1 – x epitaxial thin films and demonstrated the spin accumulation effect in multiterminal devices based on Fe3 + xSi1 – x/Si. Fe3 + xSi1 – x/Ge/Fe3Si and Fe3 + xSi1 – x/Ge/Mn5Ge3 multilayer hybrid structures were synthesized on a Si(111) substrate, study of their structural, magnetic and transport properties were performed. The effect of synthesis conditions on the growth of epitaxial structures and on their magnetic and transport properties was discussed. The results obtained may prove valuable in the development and fabrication of spintronic devices.

Аннотация:
Three-layer iron-rich Fe3+xSi1-x/Ge/Fe3+xSi1-x (0.2 < x < 0.64) heterostructures on a Si(111) surface with Ge thicknesses of 4 nm and 7 nm were grown by molecular beam epitaxy. Systematic studies of the structural and morphological properties of the synthesized samples have shown that an increase in the Ge thickness causes a prolonged atomic diffusion through the interfaces, which significantly increases the lattice misfits in the Ge/Fe3+xSi1-x heterosystem due to the incorporation of Ge atoms into the Fe3+xSi1-x bottom layer. The resultant lowering of the total free energy caused by the development of the surface roughness results in a transition from an epitaxial to a polycrystalline growth of the upper Fe3+xSi1-x. The average lattice distortion and residual stress of the upper Fe3+xSi1-x were determined by electron diffraction and theoretical calculations to be equivalent to 0.2 GPa for the upper epitaxial layer with a volume misfit of -0.63% compared with a undistorted counterpart. The volume misfit follows the resultant interatomic misfit of |0.42|% with the bottom Ge layer, independently determined by atomic force microscopy. The variation in structural order and morphology significantly changes the magnetic properties of the upper Fe3+xSi1-x layer and leads to a subtle effect on the transport properties of the Ge layer. Both hysteresis loops and FMR spectra differ for the structures with 4 nm and 7 nm Ge layers. The FMR spectra exhibit two distinct absorption lines corresponding to two layers of ferromagnetic Fe3+xSi1-x films. At the same time, a third FMR line appears in the sample with the thicker Ge. The angular dependences of the resonance field of the FMR spectra measured in the plane of the film have a pronounced easy-axis type anisotropy, as well as an anisotropy corresponding to the cubic crystal symmetry of Fe3+xSi1-x, which implies the epitaxial orientation relationship of Fe3+xSi1-x (111)[0-11] || Ge(111)[1-10] || Fe3+xSi1-x (111)[0-11] || Si(111)[1-10]. Calculated from ferromagnetic resonance (FMR) data saturation magnetization exceeds 1000 kA/m. The temperature dependence of the electrical resistivity of a Ge layer with thicknesses of 4 nm and 7 nm is of semiconducting type, which is, however, determined by different transport mechanisms.

Аннотация:
With the rapid development of telecommunication technologies and highly integrated electronic devices, researchers show great interest in nanocrystalline soft magnetic thin films with unique characteristics for microwave applications. An important direction of the current research in this field is the study of high-frequency magnetization dynamics that directly depends on the damping processes in a magnetic medium. This paper reports on the effect of sharp broadening and shift of the ferromagnetic resonance (
FMR
) line revealed experimentally in a 40-nm-thick nanocrystalline permalloy (Fe20Ni80) thin film at a frequency of about 5 GHz. The effect arises only in films with crystallite size exceeding some critical value Dcr. The micromagnetic simulation demonstrates that exchange and dipolar interactions between randomly oriented crystallites form in the film a quasiperiodic magnetic structure with a characteristic wavelength in the range from 36 nm to 3.3 µm. An analysis of the two-magnon scattering model and simulation results shows that the formed magnetic structure provides the energy transfer from uniform magnetization oscillations (uniform
FMR
) to spin waves, which results in an additional energy dissipation channel and, consequently, sharp
FMR
line broadening. A theoretical estimate of the critical crystallite size Dcr based on this model yields a value of ~14.3 nm for 40-nm-thick Fe20Ni80 films.

Аннотация:
The stability of a catalyst for partial H2S oxidation has been studied by the ferromagnetic resonance (
FMR
) technique combined with transmission electron microscopy, X-ray diffraction, Mössbauer spectroscopy, and magnetostatic investigations. The ε-Fe2O3 iron oxide nanoparticles supported on silica have been examined for their stability under the selective H2S oxidation conditions. The combination of the physicochemical methods has been used to study the state of reacted catalysts. The ε-Fe2O3 phase has been found to remain stable under the selective H2S oxidation conditions at temperatures up to 300 °C. The active phase state during the catalytic reaction has been explored using in situ
FMR
experiments. It has been established that the ε-Fe2O3 nanoparticles retain their structure and magnetic properties in the presence of H2S at high temperatures. During the in situ
FMR
experiments, the ε-Fe2O3 sulfidation process has been studied.

Аннотация:
The ϵ-Fe2O3 iron oxide polymorph is a well-known magnetic material with a complex magnetic structure, which undergoes a series of magnetic transitions in different temperature ranges. However, the ϵ-Fe2O3 phase diagram is still unclear. We report on the magnetic properties of a sample consisting of ϵ-Fe2O3 nanoparticles with an average size of 8 nm embedded in a SiO2 xerogel matrix without an admixture of foreign phases. Along with the features typical of the well-known ϵ-Fe2O3 magnetic transition in the temperature range 80–150 K, the temperature dependence of magnetization M(T) of ϵ-Fe2O3 includes other low-temperature anomalies. In an external field of H = 70 kOe, there is a noticeable temperature hysteresis of magnetization at 50–90 K, and near T ≈ 50 K, the M(T) curves have a characteristic bending, which may be indicative of an additional magnetic transition. The ferromagnetic resonance spectra shows that, near 500 K, a magnetic phase transition occurs, which was previously thought to be a transition to the paramagnetic state. An analysis of the temperature dependence of the ferromagnetic resonance spectra shows that the magnetically ordered phase in ϵ-Fe2O3 exists up to about 800 K.

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.

Аннотация:
Продемонстрирован новый метод измерения спектров ФМР, основанный на регистрации параметров полюса затухания на амплитудно-частотной характеристике двухзвенной микрополосковой структуры, содержащей исследуемый образец. Полюс затухания (ноль прохождения) образуется вследствие компенсации емкостного (электрического) и индуктивного (магнитного) взаимодействий между резонаторами структуры, и эта компенсация нарушается в условиях ФМР.
A new technique for measuring
FMR
spectra is demonstrated, which is based on the registering a damping pole in the frequency response of two-resonator microstrip structure containing a sample under investigation. A damping pole (transmission zero) arises due to mutual compensation of capacitive (electric) and inductive (magnetic) interactions between the resonators, and this compensation get broken in the
FMR
conditions.

Аннотация:
Using ferromagnetic resonance method, we performed measurements of two-dimensional periodic arrays of disc-shaped cobalt particles with different diameters a=450 and 900 nm and the distance between them l=2a and 3a with temperature variation in the range T = 140 −300 K. The first derivative of the microwave absorption spectrum was registered. With the increase of T additional peaks on both sides from the main peak that move aside from it, all peaks show an increase of the intensity and a decrease of the width. Dependences of the resonance field on T shows saturation-like behavior with increasing temperature. They move to higher temperatures and show sharper behavior with a increase and l decrease, respectively. An increase of a leads to the intensity decrease and width increase of all three adsorption peaks.

Аннотация:
Dielectric resonances in the 37-42 GHz frequency band in the single crystal barium hexaferrite that occur well below the ferromagnetic resonance (
FMR
) have been investigated. Sample dimensions have been chosen so that the mode frequency is lower than the spin-wave excitation (in this case, the natural domain resonance) frequency. Such dielectric mode frequencies, being a function of both permittivity and permeability, are magnetic field H tunable. Here, we report on below-
FMR
magnetodielectric resonance (MDR) axially magnetized barium hexaferrites and their H-tuning characteristics. Our studies reveal H-tuning by up to 2.5 GHz and the tuning is the largest when the ferrite is in a magnetically unsaturated state. A theory for the MDR is presented and a fairly good agreement between experimental data and theory has been obtained. Tunable millimeter wave phase shifters and isolators utilizing the below-
FMR
dielectric resonances have been demonstrated.

Аннотация:
Fused silica plates have been implanted with 40 keV Co+ or Ni+ ions to high doses in the range of (0.25-1.0) x 10(17) ions/cm(2), and magnetic properties of the implanted samples have been studied with ferromagnetic resonance (
FMR
) technique supplemented by transmission electron microscopy, electron diffraction and energy dispersive X-ray spectroscopy. The high-dose implantation with 3d-ions results in the formation of cobalt and nickel metal nanoparticles in the irradiated subsurface layer of the SiO2 matrix. Co and Ni nanocrystals with hexagonal close packing and face-centered cubic structures have a spherical shape and the sizes of 4-5 nm (for cobalt) and 6-14 nm (for nickel) in diameter. Room-temperature
FMR
signals from ensembles of Co and Ni nanoparticles implanted in the SiO2 matrix exhibit an out-of-plane uniaxial magnetic anisotropy that is typical for thin magnetic films. The dose and temperature dependences of
FMR
spectra have been analyzed using the Kittel formalism, and the effective magnetization and g-factor values have been obtained for Co- and Ni-implanted samples. Nonsymmetric
FMR
line shapes have been fitted by a sum of two symmetrical curves. The dependences of the magnetic parameters of each curve on the implantation dose and temperature are presented.
