The diffusion mode of the non-steady-state photo-EMF excitation is investigated in periodically poled MgO:LiNbO₃ crystal at light wavelength λ=457 nm. The signal excitation is carried out along the polar axis of the crystal; the dependencies of the signal amplitude versus the phase modulation frequency, intensity and spatial frequency of the interference pattern are studied in this geometry. The analysis of these dependencies allows determining the photoelectric parameters of the material – the type, value and relaxation time of the photoconductivity, as well as the diffusion length of charge carriers.

The influence of the shape parameter (oblateness) of a uniaxial ellipsoidal nanoparticle on the dynamics of its magnetic moment upon magnetization along the symmetry axis and excitation by a weak transverse high-frequency field in the region of parameters where the equilibrium magnetic moment of the nanoparticle and the external static field is noncollinear has been studied. It is shown that as the oblateness increases, the irregularity of the oscillations increases, which at first affects only their amplitude, but then also the time dependence. The intervals of the shape parameter (or frequency), where various nonlinear modes of precession are realized - dynamic bistability, complex spatial attractors and chaos, were revealed using bifurcation diagrams.

The mechanical properties and thermal conductivity of a composite based on crumpled graphene flakes and nickel nanoparticles obtained by high-temperature hydrostatic compression are investigated by the method of molecular dynamics. The pores of the graphene matrix of the composite are filled with nickel nanoparticles of different sizes (respectively, different contents of Ni - 8, 16 and 24 at.%). It was found that an increase in the amount of nickel on the one hand increases the thermal conductivity of the composite, and on the other hand reduces its strength, since strength is determined by the presence of a graphene grid, and thermal conductivity is determined by the presence of a conductive metal. The obtained results on thermophysical properties combined with high mechanical characteristics of Ni/graphene composites allow us to predict their application for the manufacture of new flexible electronics, supercapacitors and lithium-ion batteries.

It is devoted to the experimental study of the creep of an aluminum alloy containing microscopic inclusions. It was found that preliminary electric ignition (j<3· 106 A/m2) of the material leads to an increase in the creep of the samples. The reasons for the observed changes are associated by the authors with the formation of local areas of high mechanical stresses near the interface of the inclusion - matrix interface. The assessment of the level of emerging local thermoelastic stresses in aluminum deltaT ~ 35 MPa, as well as the characteristic size of such areas (~ 2 µm). The observed increase in creep is determined by the resultant effect of residual stresses and stresses of thermal nature, which contributes to the creation of additional local sources of deformation in the interfacial regions. Local stress concentrators lead to a local increase in the number of mobile dislocations, which is the main reason for the change in the mechanical properties of the aluminum alloy under consideration with microscopic inclusions.

The features of the microstructure of radiant spherulites in lead zirconate titanate thin films are studied using scanning electron and nonlinear optical microscopy by varying the blocks size of the perovskite structure. It is shown that with an increase in the radius of the spherulite (or the size of blocks), the angle of rotation of the growth axis increases, the speed of the angle of rotation, and the magnitude of the signal of the second optical harmonic It is assumed that the reasons determining specifics of the structure and signal of the second optical harmonic are associated with a change in the magnitude of mechanical stresses in the films that arise due to a change in the phase density at perovskite phase crystallization from low-temperature pyrochlore phase or at perovskite phase recrystallization

In this paper, the effect of the orientational stretching rate on the piezoelectric properties and structure of the vinylidene fluoride-tetrafluoroethylene P(VDF-TFE) copolymer was studied. A relationship in the formation of the electret and piezoelectric states in P(VDF-TFE) has been established. The parameters of electrically active defects involved in the polarization process and determining the stability of the electret and, as a consequence, the piezoelectric states in P(VDF-TFE) are calculated.

A vortex lattice in a high-temperature superconductor (HTS) with an array of submicron magnetic dots on the surface has been studied by the Monte Carlo method within the framework of a three-dimensional model of a layered high-temperature superconductor. The adjustment of the vortex lattice to an array of magnetic points was observed — ordered states arising in the process of remagnetization — configurations of one, two, three, or more vortex filaments fixed to a single magnetic point. The occurrence of these configurations was accompanied by peaks on the magnetization curve. The influence of the HTS anisotropy on the adjustment of the vortex lattice is analyzed. The ordered configurations of the vortex lattice are also associated with the non-monotonic nature of the dependences of the superconductor critical current on the magnetic field. The influence of temperature, magnetic moment of points, and film thickness on the critical current is investigated. With an increase in temperature and a decrease in the magnetization of magnetic points, the maximum of the critical current shifts towards a lower field. The structure of vortex filaments in the inhomogeneous field of a magnetic point is analyzed in detail. The mechanism of the influence of ordered vortex configurations on magnetization and critical current is discussed.

For the first time, changes in lattice parameters (metrics) during a structural transition in stoichiometric cobalt TmBaCo4O7+x with x~ 0 (iodometric titration method) obtained by quenching from 900-950oC were investigated by direct X-ray method. It was found that during the structural transition TS~220-240 K, the Delta a/a parameter does not detect any features, parameters b and c experience jumps of different sign and different magnitude Delta b/b~3.5·10-3 and Delta c/c~-4.0·10-3, which leads to a jump in the volume of Delta V/V~ -0.5·10-3. The distortion value eo ~ -3.5·10-3 remains constant with increasing temperature and disappears abruptly during the transition.The distortion of the structure is accompanied by abnormal behavior of the Young's Delta E(T)/E0 module in the TS region. In the region of the expected magnetic phase transition of the cobalt subsystem, anomalies on the Young's modulus curve Delta E(T)/E0 were not detected, and a strong absorption peak at T~ 96 K on the internal friction dependence q-1(T) is, apparently, a sign of a developed short-range order.

The study of grown Sc 2 SiO 5 :Gd and Sc 2 SiO 5 :Fe crystals was carried out by the paramagnetic resonance method. It has been established that Fe 3+ ions replace Sc 3+ in both crystallographic positions, while Gd 3+ ions exhibit a single center localized in a larger position with a coordination number of 7. Measurement of the orientational behavior of the positions of transitions of Fe 3+ and Gd 3+ centers in two orthogonal planes made it possible to determine the parameters of their triclinic spin Hamiltonians. To determine the localization of impurity ions Cr 3+ , Fe 3+ , and Gd 3+ in scandium and yttrium silicates, the orientation of the main Z axes of the fine structure tensors of the second rank was used.

The influence of the period filling parameter in the lateral system planar waveguide/corrugated waveguide is investigated by the method of micromagnetic modeling. The modes of switching the propagation of spin waves to the output ports are shown. When a defective region is added to the system - a region without periodicity - the transmission spectrum changes, and additional frequency regions of wave transmission appear. Based on the results obtained, it is possible to create a directional coupler applicable to information signal processing devices based on the principles of magnonics.
