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).

Заглавие : Synthesis and magnetic properties of (CoNiPsoft/CoP hard) n multilayers
Место публикации : Bull. Russ. Acad. Sci.: Phys. - 2013. - Vol. 77, Is. 9. - P.1106-1107. - ISSN 1062-8738, DOI 10.3103/S1062873813090359
Аннотация: Magnetic interactions in Co-Ni-P multilayers consisting of alternating magnetically soft and magnetically hard layers are investigated experimentally. Variations in the shape of magnetization hysteresis loops upon the conjugation of magnetically soft and hard layers are found, along with saturation field oscillations that depend on the number of layer pairs.

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
Коллективы : International Conference on Mechanical Engineering, Automation and Control Systems

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.

Заглавие : Spontaneous magnetization and characteristics of temperature-induced magnetization of planar Co/Si nanostructures

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 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)).
