Summary: The magnetic behavior of BiFeO3 nanoparticles was studied using First-Order Reversal Curve (FORC) and temperature-dependent magnetometry measurements. It was found that below a certain size, the nanoparticles exhibit ferromagnetic-like behavior, while above that size, a paramagnetic contribution dominates.

Summary: Ceramic Bi1-xNdxFeO3 solid solutions with doping concentration ranging from 0.10 to 0.20 were prepared to investigate their structural evolution and magnetic properties. The study revealed a transition from polar rhombohedral to antipolar orthorhombic structures, along with the emergence of weak ferromagnetism at high doping concentrations due to the destruction of the cycloidal spin structure. Additionally, magnetic aging behavior at room temperature confirmed the contribution of phase boundary spins to the magnetic properties.

Summary: Emission Fe-57 Mossbauer spectroscopy was used to study the temperature dependence of the hyperfine magnetic field in Ba-doped BiFeO3 thin films. The measurements were performed on two samples, 88 nm and 300 nm thick, and doped to 15% with Ba ions. The results showed a variation of the hyperfine field with temperature following the Brillouin curve for S = 5/2.

Summary: The study investigates the dielectric properties and DTA signal of composite ceramics (BiFeO3)(1-)(x)/(BaTiO3)(x) (x = 0, 0.25, 0.50, 0.75) from 300 to 720 K. The results show that the Neel temperature determined at the peaks of dielectric constant near the antiferromagnetic phase transition in (BiFeO3)(1-)(x)/(BaTiO3) shifts towards lower temperatures with increasing barium titanate content, as confirmed by the movement of DTA signal peaks.

Summary: In this study, remarkable strain-modulated magnetic properties were demonstrated in chemically vapor deposited Cr2Te3 nanoflakes grown on mica substrate. The Curie temperature of Cr2Te3 nanoflakes can be positively and negatively modulated under tensile and compressive strain, and the coercive field also showed a significant decrease under applied strain. This work suggests the promise of employing interfacial strain to accelerate the practical application of room temperature 2D magnetics.

Summary: The study investigates the structural and magnetic properties of Bi0.5La0.5Fe1-xCrxO3-delta compounds synthesized by solid-state reaction method. The substitution by Cr significantly influenced the morphology, crystalline, and magnetic properties of the samples, leading to an increase in crystallite size, reduction in microstrain, and abrupt changes in structural parameters. Additionally, all samples demonstrated a spontaneous large exchange bias effect at room temperature, indicating the importance of Cr doping.

Summary: This study investigates the magnetic properties of soft magnetic composites (SMCs) based on Fe/SiO2/ferrite at different temperatures. The results show that an increase in temperature affects the magnetic properties, necessitating consideration of the temperature effect. By analyzing energy losses and using the Statistical Theory of Losses, the magnetic properties at different ferrite contents and temperatures are studied. Frequency-temperature maps reveal a decrease in relative permeability values above 125 degrees C, associated with the Curie temperature of ferrite. It is found that the composite with 2% ferrite achieves excellent magnetic properties, with an initial relative permeability of 84 and energy loss of 57 J/m3.

Summary: The study presents the vector analysis of the electric field-driven antiparallel magnetic domain evolution in FeCoSiB/PMN-PT(011) multiferroic heterostructures, demonstrating the energy minimization process with uniaxial strains induced by E-fields. Additionally, it shows that magnetic domains can be switched to both 0 degrees and 180 degrees easy directions simultaneously, leading to antiparallel magnetization distribution in ferromagnetic/ferroelectric heterostructures.

Summary: The paper explores recent advances in the study of topological spin/polarization structures in ferroic materials, including the evolution of topological spin structures and exotic polar topologies in magnetic thin films and ferroelectric oxide films. It discusses the control of these structures and emergent phenomena through factors such as epitaxial strain, layer thickness, electric fields, and magnetic fields. Additionally, the paper provides a brief overview and prospectus for the future development of the field in the coming years.

Summary: Dy3+ doped indium nitride nanosheets with room-temperature ferromagnetism were synthesized via a vapor solid phase nitriding reaction. The ferromagnetic properties of the samples can be altered by the presence of doped Dy3+. The magnetic properties originate from the d-f interaction between localized carriers and adjacent rare earth Dy3+ ions, allowing for potential applications in spintronic devices.
