Summary: This study investigates the magnetic phase transition temperature of FeRh thin films and demonstrates that doping copper impurities can significantly reduce the transition temperature. The decrease in temperature is attributed to a reduction in long-range order of AFM and other factors such as lattice strain and valence electrons per atom.

Summary: This study investigated the impact of deposition temperature and impurity concentration on the physical/electrical properties and polarization switching kinetics of atomic-layer deposited Hf0.5Zr0.5O2 thin films. It was found that decreasing deposition temperature led to increased residual impurity concentration, resulting in smaller grain size and shorter polarization switching time. The lower energy barrier for nucleation of oppositely polarized domains and increased spatial inhomogeneities were attributed to this phenomenon.

Summary: Investigation of trilayer structures composed of nominally 45 nm GaN:Mg / 5 nm (Ga,Mn)N / 45 nm GaN:Mg prepared by molecular beam epitaxy on GaN-buffered Al2O3 substrates reveals that the indirect co-doping by holes from the cladding layers may not significantly alter the spin-spin interaction in (Ga,Mn)N, possibly due to the presence of residual Mn in the cladding layers. More technological efforts are suggested to promote the carrier-mediated ferromagnetic coupling in Mn-enriched GaN, particularly at elevated temperatures.

Summary: Thin films of ferromagnet Fe2Ge were successfully grown via molecular beam epitaxy, and their magnetic and electrical properties were measured experimentally. The material showed strong spin polarization, as indicated by the observed high-temperature maximum in the longitudinal resistivity and the suppression of electron-magnon scattering at low temperatures. Measurements of the Hall resistivity revealed contributions from both the ordinary and anomalous Hall effects, providing information about the charge carrier concentration and mobility. Additionally, small negative magnetoresistance was observed in both longitudinal and transverse geometries. Fe2Ge holds promise as a spintronic material due to its compatibility with semiconductors.

Summary: Recent studies have shown that electrostatic electron doping weakens the ferromagnetic intralayer order in CrI3, leading to a linear decrease in magnetization and Curie temperature with doping density. The puzzling linear doping dependence observed in n-type CrI3 requires a fine-tuned nonlinear decrease of the spin-wave gap. Using first-principles-based simulations, it is revealed that electron doping induces a quantum phase transition in CrI3, resulting in a magnetic state characterized by spontaneous spin-flip formation at the atomic scale.

Summary: We experimentally demonstrated the phase change control of Hall effects in ferromagnetic MnBi thin films at room temperature. Two distinct ferromagnetic phases were obtained using different cooling methods, and the Hall resistivity showed different characteristics between the two phases. By optimizing the ratio, the sign of the Hall resistivity can be repeatedly switched.

Summary: The study presented a single-phase multiferroic spinel CoFe1.6Al0.4O4 with ferrimagnetic and ferroelectric properties at room temperature. The CoFe1.6Al0.4O4 films exhibit a spinel structure with Fd (3) over bar m space group, showing typical ferroelectric hysteresis and significant piezoresponse displacement at room temperature. The ferroelectric order likely originates from possible atomic orderings in cationic sublattices and local deformation induced by the substitution of Al ions at the sublattices of CoFe2O4 in the CoFe1.6Al0.4O4 spinel.

Summary: The study shows that LNMO thin films maintain insulating behavior and a stable Curie temperature, regardless of the epitaxial strain conditions. This suggests that this material could be used in multi-layer device architectures that require a high-temperature ferromagnetic insulating state.

Summary: Two-dimensional transition metal dichalcogenides (2D TMDs) have promising applications in various fields, such as electronics, optoelectronics, memory devices, batteries, superconductors, and hydrogen evolution reactions. This paper reviews recent enhancement approaches to induce magnetism in 2D TMDs, including doping, vacancy defects, heterostructure composites, phase modulation, adsorption, electron irradiation, and O plasma treatment. The effects of these methods on introducing magnetism into 2D TMDs are summarized and discussed. For future research, more reliable and efficient techniques, such as exploring advanced design strategies and advancing experimentation strategies, should be directed towards magnetic doping in 2D TMDs materials.

Summary: Dilute magnetic MnGe quantum dots (QDs) have been widely studied for their potential applications in spintronics. However, their practical use at room temperature is limited due to the relatively low Curie temperature. In this study, Te-doped Mn0.064Ge0.895Te0.041/Si QDs were successfully prepared using the ion beam composite target sputtering technique. The growth temperature and deposition thickness were found to affect the density and magnetic properties of the QDs. The Te-doped QDs exhibited higher Curie temperature and magnetization due to the enhanced exchange coupling between holes and Mn atoms.

Summary: This study comprehensively characterized the nucleation and evolution of the ferromagnetic phase in the thin Fe49Rh51 film on a MgO substrate near the antiferromagnetic (AFM) to ferromagnetic (FM) phase transition, utilizing measurements of temperature, time, and magnetic field dependencies. The observed relaxation processes of magnetization indicate the nucleation of the FM phase on the film surface and its growth towards the film-substrate interface. The confirmation of FM phase growth evolution was verified through vibrational magnetometry and magnetic force microscopy methods.
