Domain structure regularization in monocrystalline barium hexaferrite

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2018
Conditions for regular domain structure formation in a monocrystalline barium hexaferrite plate have been studied experimentally. The purpose of the work was to develop a simple and, at the same time, an effective method of regularizing the cylindrical ...

Excitation of Spin Waves in Ferrimagnetic Alloy via Optical Transient Grating Spectroscopy

Advanced Photonics Research, Volume 7, Issue 2, February 2026.
The study demonstrates an all‐optical method for exciting and detecting standing spin waves in a ferrimagnetic thin film using the Transient Grating technique. By using polarization‐sensitive detection, we separate magnetic and thermoelastic dynamics.

Theoretical analysis of transcranial magneto-acoustical stimulation with Hodgkin–Huxley neuron model

Frontiers in Computational Neuroscience, 2016
Transcranial magneto-acoustical stimulation (TMAS) is a novel stimulation technology in which an ultrasonic wave within a magnetostatic field generates an electric current in an area of interest in the brain to modulate neuronal activities. As a key part

Observation of angle-dependent mode conversion and mode hopping in 2D annular antidot lattice

Scientific Reports, 2019
We report spin-wave excitations in annular antidot lattice fabricated from 15 nm-thin Ni80Fe20 film. The nanodots of 170 nm diameters are embedded in the 350 nm (diameter) antidot lattice to form the annular antidot lattice, which is arranged in a square

Electron Correlations in Local Effective Potential Theory

Computation, 2016
Local effective potential theory, both stationary-state and time-dependent, constitutes the mapping from a system of electrons in an external field to one of the noninteracting fermions possessing the same basic variable such as the density, thereby ...

Topological transition from a hopfion to a toron via flexoelectric self-polarization in chiral liquid crystals

Physical Review Research
The presence of topological defects in apolar chiral liquid crystals causes orientational distortions, leading to nonuniform strain. This nonuniform strain generates an electric polarization response due to the flexoelectric effect, which induces an ...

Magnetostatic waves in the gap between two ferromagnetic with longitudinal magnetizations that move relative to each other

Физика волновых процессов и радиотехнические системы, 2013
The propagation of a magnetostatic gap wave in a gap between two ferromagnetic with opposite longitudinal magnetizations is considered under the conditions for relative longitudinal displacement.
