Заглавие : Anisotropy of nonlinear optical transmission at the edge of the photonic band gap of an apodized layered medium
Место публикации : Optics and Spectroscopy (English translation of Optika i Spektroskopiya). - 2008. - Vol. 104, Is. 5. - P.751-755. - ISSN 0030-400X, DOI 10.1134/S0030400X08050172

Аннотация: The effect of Kerr nonlinearity on the transmission of laser radiation in a one-dimensional photonic crystal has been investigated by the transfer-matrix method, modified to describe nonlinear effects. The crystal under study is a thin-film multilayer structure with a spatial distribution of the refractive index, which makes it possible to eliminate side bands in the transmission spectrum at each side of the photonic band gap and significantly increase the slope of the transmission curve. The transmission spectrum of such a photonic crystal structure has been studied for two opposite directions of laser radiation propagation. The anisotropy of nonlinear transmission is most pronounced near the edge of the photonic crystal band gap, which lies in the near-IR region. The proposed structure, having strong transmission anisotropy and sufficiently low reflection in the forward direction, can operate as an optical diode (analog of an electron diode).

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: (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).

Заглавие : Stress-wave change in the copper structure: Covering magnetic response

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.

Аннотация: The magnetic properties of planar Co/Si nanostructures with different nominal thicknesses of the magnetic (2-42 nm) and nonmagnetic (0.3-10 nm) constituent layers are studied in the temperature range 4.2-300 K. It is established that in the presence of Si layers the spontaneous magnetization of Co decreases and its temperature dependence changes, and magnetic hysteresis is modified. The interlayer influence is interpreted as being due to the diffusion of Si into the Co layers, which results in the formation of magnetically disordered boundary interfaces with low average magnetization. The depth of the interfaces depends on the nominal thickness of the Si layers and is estimated to reach 1.6 nm. A qualitative explanation of the characteristics of the magnetization of the experimental objects under the influence of a magnetic field and temperature is given in a model where the interfaces have a granular microstructure. Electron-microscope observations confirm some assumptions of the proposed model. (C) 2007 American Institute of Physics.

Аннотация: The results of the investigation of the structural and magnetic properties of CoPd films with equiatomic composition have been presented. The films have been synthesized by vacuum annealing of polycrystalline Pd/Co and epitaxial Pd/α-Co(110) and Pd/β-Co(001) bilayer samples. It has been shown that, for all samples, the annealing to 400°C does not lead to the mixing of layers and the formation of compounds. A further increase in the annealing temperature results in the formation of a disordered CoPd phase at the Pd/Co interface, which is fully completed after annealing at 650°C. The epitaxial relationships between the disordered CoPd phase and the MgO(001) substrate are determined as follows: CoPd(110)〈1¯11|| MgO(001)〈100〉 and CoPd(001)[100] || MgO(001)[100], which are formed in the Pd/αCo(110) and Pd/βCo(001) films, respectively. According to the calculations, the first magnetocrystalline anisotropy constants of the disordered CoPd phase for Pd/αCo(110) and Pd/βCo(001) samples have close values: = –(1.6 ± 0.4) × 105 erg/cm3. A possible mechanism of the solidstate synthesis of the CoPd alloy is proposed.

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: A comparative analysis was carried out of the initiation temperatures of solid-phase reactions in bilayer solid films and the Kurnakov temperatures of the phases forming in the reaction products. It has been shown that in superstructures where ordering is usually observed, the Kurnakov temperature coincides with the initiation temperature of the solid-phase reactions if no other solid-phase structural transformation precedes the order-disorder phase transition in the state diagram. A rule was proposed by which pairs of films capable of entering into solid-phase reactions and their initiation temperatures can be determined. (C) 2001 MAIK "Nauka/Interperiodica".

Аннотация: The temperature dependence of the magnetization of (Fe/Si) (n) multilayer films with nanometer layers is investigated. The films are prepared through thermal evaporation under ultrahigh vacuum onto Si(100) and Si(111) single-crystal substrates. It is revealed that the thickness of individual iron layers in (Fe/Si) (n) multilayer films affects the magnetization and its temperature dependence. The inference is made that this dependence is associated with the formation of a chemical interface at the Fe-Si boundaries. The characteristics of the chemical interface in the (Fe/Si) (n) films are estimated.

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: Temperature, magnetic field and spectral dependences of magneto-optical effects (MOEs) in bi-layer films Dy(1-x)Nix-Ni and Dy(1-x)(NiFe)(x)-NiFe were investigated, x changes from 0 to 0.06. Peculiar behavior of the MOEs was revealed at temperatures essentially exceeding the Curie temperature of bulk Dy which is explained by the magnetic ordering of the Dy layer containing Ni under the action of two factors: Ni impurities distributed homogeneously over the whole Dy layer and atomic contact of this layer with continues Ni layer. The mechanism of the magnetic ordering is suggested to be associated with the change of the density of states of the alloy Dy(1-x)Nix owing to hybridization with narrow peaks near the Fermi level character for Ni.

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: We report our experimental observation of interlayer exchange coupling phenomena in CoO/Cu/Co trilayers with systematic variation of Cu spacer layer thickness as well as temperature. It has been found that there exists a clear indication of nonmonotonically varying oscillatory interlayer exchange coupling. The amplitude of oscillation increases, reaches to the maximum, and decreases with increasing Cu spacer thickness from 1 to 16 atomic layers for all temperature ranges between 70 and 200 K.

Аннотация: The microwave phenomena that occur in magnetic multilayer (CoFe)/Cu nanostructures, which have a giant magnetoresistance, are studied. The transmission of waves through a nanostructure is used to investigate the microwave giant magnetoresistance effect. The changes in the transmission coefficient at frequencies of 29–38 GHz are found to exceed the relative magnetoresistance, which distinguishes the system under study from the nanostructures studied earlier. Ferromagnetic and spin-wave resonances are used to study the angular dependences of the microwave absorption spectra of a multilayer (CoFe/Cu)n nanostructure. The following parameters are determined: the critical angle that determines the boundaries of the ranges of excitation of uniform and nonuniform spin modes, the type of boundary conditions describing the pinning of spins on the outer nanostructure surfaces, and the surface anisotropy and exchange interaction constants.
