Аннотация:
Simple formulas for determination of components of the scattering matrix of a plane electromagnetic wave incident along the normal onto a thin infinite 2D metal lattice with square windows placed at the interface of two media are derived for the first time. Frequency responses (FRs) of this structure calculated with the use of these formulas agree well with responses obtained by the numerical electromagnetic analysis of a 3D model in the case when the lattice period is less than one-half of the wavelength. The capability of efficient control of the FR of the analyzed structure by means of variation in the width of conductors and the lattice period enables application of this lattice for fabrication of a reflector with prescribed reflectivity. Such reflectors at interfaces of dielectric layers are required, for example, in the design of multilayer sufaces radio transparent in a specified frequency band or optical bandpass filters.

Многослойные пленчатые системы
Аннотация:
Es werden die Wechselwirkung zweier magnetischer FeNi und FeNiCo Schichten, die durch eine Si02-Schicht getrennt sind und einige Besonderheiten bei der Transmission elektromagnetischer Mikrowellen durch geschichtete dünne Magnetschichten, die durch Si02 getrennt sind, untersucht. Dabei wird gefunden, daß die Koerzitivkraft der Schichten in einem Vielschichtsystem abnimmt. Dieser Effekt wird durch lokale magnetische Wechselwirkung zwischen den magnetischen Schichten erklärt. Die Abnahme der Koerzitivkraft hängt von der Schichtdicke ab und wird durch den wechselnden Charakter der lokalen Wechselwirkung erklärt. Die Transmissions- und Reflexionskoeffizienten wurden gemessen; sie hängen von der Dicke der einzelnen Schichten und von der Gesamtdicke der ferromagnetischen Metallschichten in dem Vielschichtsystem ab. Die Transmissionskoeffizienten für Vielschichtsysteme sind wesentlich größer als bei der einzelnen Schicht. Die Transmission der Mikrowellenenergie durch die Vielschichtsysteme wird im Rahmen der gewöhnlichen Elektrodynamik erklärt.
Это взаимодействие двух магнитных слоев FeNi и FeNiCo, которые отделены друг от друга слоем Si02 и некоторые особенности при передаче электромагнитных микроволн через слоистых магнитных тонких слоев, разделенных Si02 изучены. В этом случае, было обнаружено, что коэрцитивная сила слоев уменьшается в многослойной системе. Этот эффект объясняется локальным магнитным взаимодействием между магнитными слоями. Уменьшение коэрцитивной силы зависит от толщины слоя и объясняется меняющимся характером локального взаимодействия. Были измерены коэффициенты пропускания и отражения; они зависят от толщины каждого слоя и общей толщины ферромагнитных слоев металла в многослойной системе с. Коэффициент пропускания многослойных системах значительно больше, чем в одном слое. Передача микроволновой энергии через многослойные системы объясняется в обычной электродинамики.

The effect of annealing on the magnetic properties of (Co40Fe40B20)x(SiO2)1–x granular composites fabricated via ion-beam sputtering is investigated. It is established that annealing changes the concentration dependences of the ferromagnetic resonance field and linewidth and shifts the regions of metal phase concentration corresponding to the spin-wave resonance. © 2016, Allerton Press, Inc.

Аннотация:
The work presents the results of the investigationof deformation processes occurring in copper after stress-wave influence. Structural changes analysis is carried out by direct research methods (X-ray phase analysis and optical microscopy) along and perpendicular to the spreading direction of the stress wave front in the copper foil plane. For more information, investigations have been conducted by an indirect method using ferromagnetic resonance of magnetic characteristics. As a magnetic covering, Co/Ni-type multilayer films are deposited on the copper foil, which makes it possible to apply magnetic research methods. The magnetic response of the multilayer covering correlates with the modification of the copper structure observed by direct methods. The information obtained in the course of research allows us to conclude that the wave character of the deformation processes occurring in copper is natural. The value and direction of structural modifications vary along the sample length as a function with a long-wave period is about 30 mm, which is consistent with the inhomogeneous distribution model of internal stresses. Throughout the sample length, alternating areas of stretching and compression of copper grains are fixed along the spreading direction of the stress wave front. The greatest stretching of the structural elements is observed at a distance equal to almost half the wavelength of the mechanical deformation field. Thus, the translational (shear) mode of the mechanical field of material plastic flow appears as the results of the investigation. © 2019 Published under licence by IOP Publishing Ltd.

(ZnO/SiO2)25 thin-film
multilayers
consisting of nanocrystalline ZnO layers and amorphous SiO2 spacers with a bilayer thickness from 6 to 10 nm are synthesized in a single deposition process. An analysis of the temperature dependences of the electrical resistivity of (ZnO/SiO2)25 thin films shows that, in the temperature range of 77–300 K, the dominant conductivity mechanism successively changes from hopping conductivity with a variable hopping length in a narrow energy band near the Fermi level at temperatures of 77–250 K to thermally activated impurity conductivity around room temperature. Using the obtained temperature dependences of the electrical resistivity, the effective density of localized states at the Fermi level and the activation energy of impurity levels are estimated. The effect of heat treatment on the structure and electrical properties of the synthesized films is examined. It is established that in (ZnO/SiO2)25 thin-film systems at temperatures of 580–600°C, the ZnO and SiO2 layers chemically interact, which is accompanied by destruction of the multilayer structure and formation of the Zn2SiO4 compound with a tetragonal structure (sp. gr. I-42d).

Аннотация:
A sequence of phases forming during the solid-phase reaction in Al/Pt bilayer thin films has been investigated by in situ electron diffraction. It is shown that the amorphous PtAl2 phase forms first during the solid-phase reaction initiated by heating. Upon further heating, PtAl2, Pt2Al3, PtAl, and Pt3Al crystalline phases sequentially form, which is qualitatively consistent with an effective formation heat model. The content of phases forming during the reaction has been quantitatively analyzed and the structural phase transformations have been examined.

Аннотация:
Inhomogeneous layered magnetic thin films of amorphous and nanocrystalline Со–Р and Co–Ni alloys are studied via spin-wave resonance. It is found that the formation of a magnetic potential profile specified over the coating thickness leads to characteristic modifications of the spin-wave resonance spectrum. Another important factor that determines the type of modification is the dominant magnetic parameter (the constant of magnetization or exchange coupling).

Аннотация:
The spectrum and damping of waves in partially randomized multilayer structures are calculated. A method of calculation that was proposed and demonstrated earlier, for the model of a superlattice with a harmonic dependence of its material parameters along its axis in the initial state, is extended to the case of a multilayer structure (i.e., a superlattice with sharp interfaces). One- and three-dimensional random modulations of the period are considered, and the correlation function of the superlattice is derived as a series in which each term is a product of a harmonic and a monotonically decaying function. The law of decay of the correlation function is Gaussian for smooth inhomogeneities, and has different forms for one- and three-dimensional short-wavelength inhomogeneities. The spectrum and damping of waves in the superlattice described by this correlation function are found in the weak-coupling approximation in the vicinities of all of the odd Brillouin zone boundaries. Analytical dependences of the main characteristics of the spectrum and damping on the zone number n are obtained. The conditions for the closing of the gaps at the Brillouin zone boundaries are derived, and depend on the dimensionality of the inhomogeneities and the degree of their smoothness.

Аннотация:
The self-propagating high-temperature synthesis in the two-layer and multilayer Pt / Co(001) thin films has been investigated. It is shown that the initiation of the synthesis occurs at temperatures of 770-820 K. After the synthesis in the two-layer film samples, the PtCo(001) disordered phase exhibits an epitaxial growth at the interface between cobalt and platinum layers. In the multilayer Pt/Co(001) thin films, the self-propagating high-temperature synthesis also brings about the formation of the PtCo(001) disordered phase on the MgO(001) surface. Further annealing at a temperature of 870 K for 4 h results in the transition of the PtCo(001) disordered phase to the ordered phase. Rapid thermal annealing of the Pt/Co(001) multilayer films at a temperature of 1000 K leads to the formation of the CoPt3 phase. The magnetic characteristics change in accord with the structural transformations in Pt/Co film samples. (C) 2000 MAIK "Nauka/Interperiodica".

Аннотация:
The recent results of the studies of magnetic materials using synchrotron irradiation are reviewed. The influence of magnetic effects on X-ray scattering is studied for linearly and circularly polarized photons, and effects of magnetic circular dichroism on the spectra of X-ray absorption and photoelectron emission are discussed. It is shown that X-ray magnetooptics techniques provide fine details of crystal and magnetic structures and also make it possible to separate the spin and orbital contributions to the total moment; to obtain element- and position-sensitive information on the magnetic properties of the material; to visualize domains and domain walls; and to probe magnetization reversal dynamics. A comparison of magnetic neutron and X-ray methods is given.

Аннотация:
The spectrum of standing. spin waves has been detected by the ferromagnetic resonance method in NiFe(740 angstrom)/Cu/NiFe(740 angstrom) three-layered film structure in the perpendicular configuration for the copper thickness d(Cu) 30 angstrom, the resonance absorption curve is a superposition of two spinwave resonance spectra from individual ferromagnetic NiFe layers. For Co/Pd multilayer films, united spinwave resonance spectra have also been observed at thicknesses of the paramagnetic palladium layer up to d(Pd) 30 angstrom. The partial exchange stiffness has been calculated for a spin wave propagating across the Pd layer (A(Pd) d(c)).

Аннотация:
Cross Correlations between components of a mixture of one-dimensional (I D) and three-diniensional (3D) inhomogenetics are described by introducing a distribution function taking into account correlations between absolute values of two random variables in the absence of correlations between the variables themselves. This distribution function is used for derivation and analysis of the superlattice correlation function containing a mixture of cross-correlated 1D and 3D in homogeneitics. The effect of such inhomogeneities on the high-frequency susceptibility at the edge of the first Brillouin zone of the superlattice is investigated. It is shown that positive cross correlations partly suppress the effect of a mixture of 1D and 3D inhomogeneities on the wave spectrum: the gap at the boundary of the Brillouin zone increases, and wave damping decreases as compared to the effect produced by a mixture of 1D and 3D inhomogeneities in the absence of cross correlations. Negative cross correlations lead to the opposite effect: the gap decreases and wave damping increases. Cross correlations also lead to the emergence of new resonance effects: a narrow dip or a narrow peak at the center of the band gap (depending on the sign of the correlation factor).

Аннотация:
The spectrum of standing exchange magnon wave in FeNi alloy films obtained by thermal evaporation method is studied. The modification of dispersion law conditioned by magnetization fluctuations is detected. The films of invar structure having metastable bcc structure are most dispersing relative to magnetic state. The size of magnetic inhomogeneity was less than 5 nm.

Аннотация:
FMR and SWR spectra of exchange-coupled structures NiFe/Ag/NiFe have been investigated. We revealed that the optical satellites of the exchange spin-wave modes are characterized not by the standard Kittel-dependence but rather by their own resonance field dependence on the mode number: Hr opt(n)?n5/2.

Аннотация:
The structural, electrical, magnetic, magneto-optical properties and magnetoresistance of {[(Co40Fe40B20)34(SiO2)66]/[ZnO]}n multilayer structures, where n = 50 is the number of bilayers (Co40Fe40B20)34(SiO2)66 nanocomposite and ZnO have been studied. The thicknesses of (Co40Fe40B20)34(SiO2)66 nanocomposite layers as well as ZnO spacers were varied in a wide range. The samples were synthesized by ion-beam sputtering onto glass ceramic substrates. The (Co40Fe40B20)34(SiO2)66 composite have an amorphous structure and the semiconductor ZnO interlayers have a hexagonal crystalline structure with the p63mc symmetry group. The nanocomposite layers containing a ferromagnetic component far from the percolation threshold are in a superparamagnetic state. The presented in the paper data of magnetization, magneto-optical transverse Kerr effect and magnetoresistance indicates that long-range ferromagnetic order does not form down to 77 K both for references ZnO films and studied
multilayers
with thin and thick ZnO interlayers. An increase in the magneto-optical signal in
multilayers
compared to references (Co40Fe40B20)34(SiO2)66 composite films has been detected at 1.2 eV. The magnetoresistance of {[(Co40Fe40B20)34(SiO2)66]/[ZnO]}n
multilayers
with thick (>32 nm) ZnO interlayers is lower than in reference (Co40Fe40B20)34(SiO2)66 nanocomposite, while at thin ZnO interlayers magnetoresistance is significantly higher and reaches 12 % at temperatures of 77 К. Possible mechanisms of ferromagnetic and antiferromagnetic ordering, enhancement of the magneto-optical response and magnetoresistance in {[(Co40Fe40B20)34(SiO2)66]/[ZnO]}n multilayer nanostructures are discussed.
