Summary: In this study, we systematically investigated the magnetic and magnetocaloric properties as well as the universal behavior of magnetocaloric effect (MCE) for polycrystalline (Nd0.5Sm0.5)0.5Sr0.5MnO3 compound. We proposed the universal behavior of magnetic entropy change for conventional magnetocaloric effect (CMCE) materials with second order phase transition and constructed a universal master curve for MCE in our system by rescaling the temperature axis.

Summary: The crystal structure, magnetic and magnetocaloric properties of polycrystalline Er3AlC compound were investigated in this study. It was found that Er3AlC has an inverse perovskite structure and exhibits two magnetic transitions: antiferromagnetic-ferromagnetic below 2 K and ferromagnetic-paramagnetic around 4.1 K. The maximum magnetic entropy changes of Er3AlC are 13.9 J/kg K and 30.5 J/kg K under the field changes of 0-2 T and 0-5 T, respectively. The large magnetic entropy change under low fields makes Er3AlC a potential candidate for cryogenic magnetic refrigeration.

Summary: An off-stoichiometric Ni-Mn-In Heusler alloy was synthesized and studied for its magnetocaloric and magnetoresistive properties. The alloy exhibited co-existing austenite and martensite phases at room temperature. A metamagnetic transition was observed near the martensite transformation temperature, resulting in negative sloped-Arrott curves. The alloy also showed large magnetoresistance and moderate entropy change around the austenite-ferromagnetic transition. The Ni48Ag2Mn37In13 alloy demonstrated significant room temperature magnetocaloric effect and low thermal and magnetic hysteresis.

Summary: This Letter demonstrates the enhancement of the unidirectional spin Hall magnetoresistance (USMR) effect by reducing the Curie temperature TC of the ferromagnetic (FM) layer in a FM/platinum bilayer. The USMR ratio is maximized when the thickness of each FM layer is consistent with the spin diffusion length. By replacing Ni81Fe19 with Ni85Cu15 as the FM material, the maximum USMR ratio can be doubled. This enhancement of the USMR effect is attributed to an increase of electron-magnon scattering in accordance with Bloch law. The use of ferromagnets with face-centered-cubic structures, such as Ni, Ni81Fe19, and Ni85Cu15, increases the USMR effect compared to body-centered-cubic Fe.

Summary: This study reports the observation of Rashba-Edelstein magnetoresistance (REMR) in single layer graphene (SLG) and 2D semiconductor MoS2 at room temperature. The direct and inverse Rashba-Edelstein effects in a YIG/2DM structure couple current-induced spin accumulation to the electric resistance, producing the REMR. The measured REE lengths for the two materials agree well with values obtained using the electric spin pumping technique.

Summary: The study found that the critical field required for the ultra-sharp jump decreases with the increase of 'Sr' concentration, leading to an increase in phase separation. Experiments show that the jump from antiferromagnetic to ferromagnetic state has martensitic nature. Numerical calculations indicate that 'Sr' doping induces ferromagnetic clusters in the antiferromagnetic insulating phase.

Summary: We designed reversible multi-level resistance states in a half-doped charge-ordered manganite, SCSMO, by exploiting electronic phase separation. During thermal cycling, the system can be stabilized into several metastable states where magnetization and resistivity remain unaltered. Monte Carlo calculations suggest that the system freezes into a phase-separated metastable state due to disorder, outlining a pathway to control multi-level switching between four reversible metastable states.

Summary: The electronic structure and ferroelectric-ferromagnetic coupling properties of Y-doped and vacancy-containing GaN-ZnO heterojunctions are systematically investigated. The magnetism in vacancy-containing systems is generated by the spin polarization of unpaired electrons induced by cationic vacancies, while in Y-doped systems, bound magnetic polarons are formed by the orbital hybridization of s-state and d-state electrons of Y-doped elements.

Summary: The elementary excitations spectrum of anisotropic frustrated antiferromagnets in the fan phase is discussed. It is found that the low-energy part of the spectrum consists of a gapless phason branch with linear dispersion and a gapped optical branch corresponding to the fan structure amplitude oscillations. In the high-energy part of the spectrum, the excitations are similar to the magnons of the fully polarized phase.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
