In this work, we present the results of investigations performed on hematite (α-Fe2O3), which is an antiferromagnet with weak ferromagnetism. Through the use of Brillouin light scattering spectroscopy, we studied experimentally the excitation of quasi-ferro- and antiferromagnetic modes in the bulk hematite. We investigated the influence of relative mechanical strains, ϵyy, on the frequencies of quasi-ferro- and antiferromagnetic modes. Also, we considered the angular dependence of the frequency of the quasi-ferromagnetic mode on the external magnetic field. Our results indicate that hematite is a suitable material for strain-controlled magnonic devices.

Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

A discrete-time model is presented for the self-organization of the X/Twitter social network to the edge of a phase transition, characterized by avalanche-like propagation of information in the network. The model is based on the analogy between the critical dynamics of the X social network and sandpile cellular automata with Manna rule on the Chung-Lu ...

Superconducting properties of metallic micro- and nanowires can be entirely different from those of bulk superconductors. Of particular interest is the nonequilibrium current-induced state of a quasi-one-dimensional superconducting channel. The most interesting phenomenon here is the stepped I–V characteristic, explained by a process known as phase slip center activation. If the origin of such step-like ...

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

This paper compares the ranging precision of direct time-of-flight (dToF) and non-line-of-sight (NLOS) LiDAR architectures, both using a superconducting nanowire single-photon detector (SNSPD). Both systems operate at 1550 nm with a 50 ps pulsed laser and time-correlated single-photon counting (TCSPC). The dToF configuration achieved approximately 100 µm precision at 10 m, while the NLOS configuration achieved 500 µm precision for ...

Исследован спиновый транспорт в антиферромагнитных проводниках. Спиновый ток инжектировали из ферромагнитной пленки Co в антиферромагнитный проводник FeMn, после чего было исследовано постоянное напряжение, возникающее в слое Pt в условиях ферромагнитного резонанса при различных углах поворота ориентации постоянного магнитного поля в плоскости пленки. Был рассчитан вклад, вызванный чистым спиновым током (спиновой накачкой), зарегистрированный с помощью обратного ...

Two-dimensional (2D) chromium telluride Cr2Te3 exhibits strong ferromagnetic ordering with high coercivity at low temperatures and paramagnetic behavior when approaching room temperature. The spin states of monolayer Cr2Te3 show ferromagnetic ordering in the ground state. In situ Raman analysis reveals a reversible structure transformation and hence proves ferromagnetic to paramagnetic transition during low-temperature heating cycles (0–25 °C). The magnetic ...

Исследовано влияние толщин ферро- и антиферромагнитных слоев на магнитные свойства синтезированной структуры Pt/Co/FeMn/Pt на кремниевой подложке SiO2. Для экспериментального и теоретического исследования использовали петли магнитного гистерезиса, угловые зависимости спектров ферромагнитного резонанса и выражение для резонансного поля, полученное в ходе решения уравнения Ландау–Лифшица для динамики намагниченности. Установлены величины коэрцитивного поля, а также полей однонаправленной и одноосной анизотропии при толщинах антиферромагнитного слоя 5, ...

Layered van der Waals crystals of topologically non-trivial and trivial semimetals with antiferromagnetic (AFM) ordering of magnetic sublattice are known to exhibit a negative magnetoresistance that is well correlated with AFM magnetization changes in a magnetic field. This effect is reported in several experimental studies with EuFe2As2, EuSn2As2, EuSn2P2, etc., where the resistance decreases quadratically with field by about ...

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 ...

Spin pumping from canted antiferromagnets is a cutting-edge topic in modern spintronics. The interest for fundamental and applied research that these materials arouse is related to their unusual structure, namely, with a small canting of the magnetic sublattices, which is explained by the presence of the Dzyaloshinskii–Moriya interaction. Through this effect, it becomes possible to experimentally study ...

Canted antiferromagnets offer great potential in fundamental research and for use in applications due to their unique properties. The presence of the Dzyaloshinskii–Moriya interaction (DMI) leads to the existence of a weak ferromagnetic moment at room temperature. We study both theoretically and experimentally microwave spin pumping by a quasi-ferromagnetic mode from a canted easy plane antiferromagnet with weak ferromagnetism ...

Microwave spin pumping from ferromagnetic lutetium iron garnet (Lu3Fe5O12) has been theoretically and experimentally investigated. The magnetization vector precession excited by a microwave magnetic field is transformed into a dc voltage due to the inverse spin Hall effect in the lutetium iron garnet/heavy metal heterostructure (Lu3Fe5O12/Pt). In the experiments carried out, the external magnetic field has been varied ...
