A series of SrMnO₃/La₀.₇Sr₀.₃MnO₃ heterostructures with different thicknesses of the antiferromagnetic SrMnO₃ layer were grown by magnetron sputtering. The magnetic characteristics of the SrMnO₃/La₀.₇Sr₀.₃MnO₃ heterostructure, including the magnitude of unidirectional anisotropy at various thicknesses of the antiferromagnetic SrMnO₃ layer, were determined using ferromagnetic resonance. The results of X-ray structural analysis of the obtained samples are presented, and the change in the magneto-optical effect in the La₀.₇Sr₀.₃MnO₃ ferromagnetic film upon deposition of the antiferromagnetic SrMnO₃ layer is estimated. The domain structure in an external magnetic field was studied using magnetic force microscopy. V-shaped magnetic domain structures, controlled by small magnetic fields, were observed in the SrMnO₃/La₀.₇Sr₀.₃MnO₃ heterostructures.

Bright transient objects in different wave bands have been discovered in recent years.
To explain these short (from ms to s), and very powerful events, different models, galactic and
extragalactic, have been considered. One of the popular models is based on the suggestion of
transformation of the magnetized plasma blob, presumably a magnetohydrodynamic (MHD)
shock wave, moving with relativistic ...

The results of MHD simulations of supersonic astrophysical and laboratory jets in an external

matter is collimated by the magnetic field, the degree of collimation and the flow structure depend on the

During magnetospheric perturbations a relatively thin current sheet with thickness about several
proton gyroradii forms in the Earth’s magnetotail. In a framework of the kinetic model describing current
sheet thinning in the magnetotail, the processes of its formation are investigated depending on the normal
magnetic field magnitude which affects both the current sheet structure and particle dynamics within ...

The influence of asymmetry of plasma sources on the structure and spatial localization of a superthin
current sheet (STCS) supported by demagnetized electrons is studied using a self-consistent model. The
simulation takes into account the presence of a single plasma source in the northern hemisphere, which
makes the plasma flow asymmetric. It is demonstrated that the asymmetry of ...

A model of the cathode layer of a glow gas discharge with a thin dielectric film on a fraction of the

Plasmonic nanostructures typically exhibit shifts in their resonant wavelength in response to changes in the refractive index of the surrounding medium. This limits their applications in scenarios requiring stable optical resonances. Here we present a metallic-dielectric hybrid metasurface that exhibits stable multi-wavelength resonance even if the refractive index of its surrounding varies. To quantitatively evaluate the stability of ...

We present a simple model that simulates the possible influence of one society on another. Specifically, two societies evolve deterministically according to the well-known Nowak-May spatial game with the addition of mutual influence through connections that reflect the current states of the societies. This may be related to the influence of a global information resource ...

We perform a Monte Carlo analysis of the Ising model on many three-dimensional lattices. By means of finite-size scaling we obtain the critical points and determine the scaling dimensions. As expected, the critical exponents agree with the three-dimensional Ising universality class for all models. The irrelevant field, as revealed by the correction-to-scaling amplitudes, appears to ...

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Svendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for two models in different universality classes: the Ising model and the Potts model with three components. The overlap of two ...

The electric double layer (EDL) governs charge distribution at electrode–electrolyte interfaces, controlling reaction kinetics and energy storage performance. This mini review surveys the evolution of EDL theory—from the classical Gouy-Chapman-Stern framework to modern coupled quantum-continuum schemes that integrate electronic structure with statistical mechanics. We show how modified Poisson–Boltzmann (mPB) formu-lations incorporating finite ion size, dielectric ...

This study presents a mean-field theory for zwitterionic polymer solutions confined within attractive slit-like nanopores. Building upon our prior model for self-coacervation [Budkov et al., Soft Matter 19, 3281–3289 (2023)], we demonstrate that strong electrostatic dipole–dipole correlations between monomeric units, coupled with attraction to pore walls, can induce capillary-driven liquid–liquid phase separation inside the pore—a ...

We have systematically examined various parameters of t- (tetragonal) and h- (hexagonal) lattices of transition metal nitride (TMN) monolayers through first-principles calculations, emphasising their structural and magnetic properties. Our study reveals that all TMN monolayers exhibit a preference for a magnetic ground state. Employing the Heisenberg model, we extract exchange interaction and magnetic anisotropy parameters. ...

Найдено, что ферромагнитный резонанс пленки и циклотронный резонанс электронов 2D системы в магнитном поле взаимодействуют, что приводит к их расталкиванию (“антикроссингу”). Обнаружено, что в области антикроссинга происходит ...
