Summary: The magnetic properties and magnetocaloric behavior of monovalent doped Pr0.75Li0.25MnO3 have been investigated. The monovalent Li doping reduces the antiferromagnetic interaction and induces a ferromagnetic component. The sample undergoes a paramagnetic to antiferromagnetic phase transition at 28K and exhibits a low-temperature negative magnetization region. The experimental magnetic entropy change curve matches well with the theoretical magnetocaloric effects curve.

Summary: The study demonstrates the reversible strain control of cycloidal spin textures in a metallic van der Waals magnet, Cr1/3TaS2, through the modulation of polarization and DMI induced by strain. The sign and wavelength of the cycloidal spin textures can be systematically manipulated with thermally-induced biaxial strains and isothermally-applied uniaxial strains, respectively. Furthermore, unprecedented reflectivity reduction under strain and domain modification at a record-low current density are also discovered.

Summary: In this study, the hierarchical autoregressive neural network sampling algorithm is applied to the two-dimensional Q-state Potts model near the phase transition at Q = 12. The performance of this approach is quantified and compared with the Wolff cluster algorithm, showing a significant improvement in statistical uncertainty with similar computational effort. The technique of pretraining is introduced to efficiently train large neural networks by using smaller system sizes as starting configurations. The results demonstrate the effectiveness of the hierarchical approach for systems with bimodal distributions, providing estimates of free energy and entropy with high statistical uncertainties.

Summary: Time and history dependent magnetization has been observed in various materials, collectively termed as glassy magnetic systems. Despite the widely held belief that the field cooled (FC) state in canonical spin glass is an equilibrium state, recent studies on two canonical spin glass systems, AuMn and AgMn, show that the FC state is not truly an equilibrium state. This is evidenced by temperature dependent magnetization and frequency dispersion in the FC state below the spin glass transition temperature, distinguishing it from other glassy magnetic systems.

Summary: Multiferroic composites show higher magnetoelectric coupling and coupled ordering parameters compared to single-phase multiferroics, making them promising candidates for magnetic field sensors, low power memory, and spintronic devices. The 3-0 type particulate composites were prepared and investigated for their multiferroic behavior, which was found to be strain-mediated domain coupling responsible for their magneto-electric behavior. Additionally, the direct ME coefficient value was higher than that of single-phase materials and polycrystalline composites.

Summary: Spin-phonon coupling in transition metal oxides, such as inverse trirutile Fe2TeO6, is studied to understand the spin-lattice correlation and its influence on magnetoelectric coupling mechanism. The study reveals short-range magnetic correlation induced by dimeric interaction, along with a magnetic anomaly at 150 K in addition to the long-range order transition. Muon spin resonance measurements show changes in spin dynamics at 150 K, despite previous studies suggesting long-range antiferromagnetic order. The renormalization of phonon frequencies and the quantified coupling strength suggest the significant role of Fe-O-2-Fe interbilayer exchange in magnetoelectric coupling observed in the material.

Summary: This study presents a sol-gel auto-combustion method to prepare core/shell structure CoFe2O4(core)/Cr2O3(shell) nanoparticles, and validates their properties through various testing methods. The nanoparticles exhibit responses similar to single domain particles under different molar fraction conditions. Impedance and modulus data analysis shows a single relaxation process in the studied frequency/temperature range, with both relaxation and conduction processes following Mott variable range hopping mechanism. Direct ME measurements demonstrate an increased magnetoelectric operating temperature for the parental Cr2O3 phase, widening its potential applications.

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.
