Аннотация: Orthorhombic PbMnBO4 is a rare example of an insulating ferromagnet in which the magnetic properties, in particular the strong magnetic anisotropy, are determined by the Mn3+ Jahn-Teller ion. Here, we report on the detailed investigation of magnetic excitations in the subterahertz and terahertz frequency ranges, as well as lattice excitations in the terahertz range. Using polarized azimuthally resolved Raman spectroscopy, four branches of magnetic excitations were observed and assigned to one acoustic and three optical one-magnon modes. The coupling between ferromagnetic ordering at TC=31K and the Jahn-Teller distortions of [MnO6] octahedra due to the spin-phonon interaction was directly observed for some specific phonon modes involved in these distortions. A spin-wave Hamiltonian was developed that allowed us to determine a unique set of exchange and effective anisotropy parameters. The intensity ratio of the anti-Stokes to Stokes acoustic magnon peaks is found to be anomalous and directly indicates the involvement of the magneto-optical parameters in the magnetic Raman scattering process.

Validation of Dobson's, Schmugge's, and Mironov's dielectric models at four typical agrosoils of Krasnoyarsk and Krasnodar krais / S. Fomin, K. Muzalevskiy, A.

Аннотация: In this article, in a wide frequency range from 300 MHz to 2 GHz at a temperature of 20C, the validation of Dobson's, Schmugge's, and Mironov's (with one, two, and three soil water relaxations) dielectric models was carried out using four samples of typical agrosoils taken from the arable layer. Variations in the clay fraction, dry bulk density, and organic matter content of soil samples ranged from 32% to 56%, from 1.1 g/cm3 to 1.7 g/cm3, up to 6.9%, respectively. It is shown that the Mironov's model with two relaxations (M2) has the best accuracy in describing the measured relative complex permittivity (RCP) spectra for all soils in average. The coefficient of determination (R2) and root-mean square error (RMSE) appeared to be equal of Rε'2=0.907 (RMSEε'=0.83) for real and Rε''2=0.960 (RMSEε'' =0.89) for imaginary parts of RCP, when comparing the measured and calculated RCPs. Error of soil moisture retrieval, based on M2 dielectric model and the observations of reflection coefficient at nadir was estimated. For four agricultural soils, it is shown that the retrieved volumetric soil moisture values with the determination coefficient R2=0.975 and RMSE =2% coincide with the true values of soil moisture. It has also been found that small inaccuracies (several tens of percent) in determining the dry bulk density and clay content of soils have practically no effect on the error in retrieving the volumetric soil moisture.

Аннотация: Herein, the AC magnetoresistance (MR) in the silicon-on-insulator (SOI)-based Fe/Si/SiO2/p-Si structure is presented. The structure is used for fabricating a back-gate field-effect pseudo-metal-oxide-semiconductor field-effect transistor (MOSFET) device. The effects of the magnetic field and gate voltage on the transport characteristics of the device are investigated. Magnetoimpedance value of up to 100% is obtained due to recharging of the impurity and surface centers at the insulator/semiconductor interface. A resistance variation of up to 1000% is found, which is caused by the voltage applied to the gate and the field effect on the band structure of the sample. Combining the magnetic and electric fields, one can either change the absolute value of the AC resistance while having the MR fixed or change the sign and character of the field dependence of the MR. The observed effects can be used in the development of magnetic-field-driven SOI-based devices and high-frequency circuits.

Nanocrystallite -- Magnetization ripple -- Ferromagnetic resonance (FMR) -- Two-magnon scattering process -- Micromagnetic simulation
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: We consider light scattering by two-dimensional arrays of high-index dielectric spheres arranged into a triangular and square lattices. We demonstrate the appearance of the double degenerate accidental super-BIC modes with extremely suppressed radiative losses in the vicinity of the Γ point of the leaky band of the triangular lattice. Two rings of BICs (circular lines of BICs in reciprocal space) with different polarization appear at the point of the super-BIC destruction. The radius of the ring BIC (RBIC) changes as a function of the sphere's radius. We propose a generic analytical expression to describe the behavior of the guided mode decay rate as a function of the sphere radii and the wave vector in the vicinity of the RBIC. The results are explained using a multipolar approach.

Аннотация: The structural phase transitions in multiferroic TbFe3(BO3)4 with change hydrostatic pressures and temperatures have been studied by Raman spectroscopy and calculation within density functional theory. Lattice dynamics calculations in the TbFe3(BO3)4 crystal in the ��32 phase under various values of applied hydrostatic pressure (from 0 up to 5 GPa with 1 GPa step) were performed. The calculation performed in this work in a TbFe3(BO3)4 crystal showed that the applied pressure can increase the phase transition temperature. Raman spectra of the TbFe3(BO3)4 crystal have been investigated at simultaneously high temperature and high pressure (up to 5.14 GPa and 465 K). The appearance of a soft mode was observed with decreasing temperature at normal pressure. The manifestations of the interaction of the structural and magnetic order parameters in the range from 13 to 50 K were observed at normal pressure. With increasing pressure and a fixed temperature, recovery of the soft modes is also observed. The experimental p–T phase diagram of TbFe3(BO3)4 was established. An increase in pressure leads to an increase in the temperature of transition.

Аннотация: We have established numerically the physical pattern and conditions for formation of nanosized bubbles in aqueous medium around biocompatible plasmonic nanoparticles (NPs) selectively bound to the membrane of the malignant cells by means of DNA-aptamers under the action of picosecond laser radiation. The results obtained are based on the finite volume method and hydrodynamic models underlying the ANSYS Fluent package with extended capabilities. We have found the main features and previously unknown dominant factors of the damage effect on the cell membrane at the moment of the bubble nucleation around the plasmonic NPs of different types taking into account the influence of the closely located membrane. Information on the kinetics of spatial distribution of pressure, temperature and the relative proportion of vapor in the 'nanoparticle-membrane-medium' system have been obtained. The attention is drawn to the advantages of using biocompatible, perfectly absorbing core–shell plasmonic NPs for anti-tumor therapy characterized by an increased mechanical effect on malignant cell membranes at lower laser radiation intensity and the spectral position of their plasmon resonance (λ = 700 nm) in the hemoglobin transparency range. This ensures penetration of laser radiation deep into tissues. The paper is provided with an extensive review of key publications and the state-of-art in this area.
