Abstract
In this work, we investigate the evolution of in-plane magnetic anisotropy in FeGa thin films as a function of post-deposition annealing temperature. FeGa films were deposited on GaN/Al2O3(0001) substrates by RF magnetron sputtering and subsequently annealed to tailor their structural ordering and composition. Room-temperature magnetic measurements reveal a strong annealing-dependent modification of anisotropy symmetry and strength, with moderate annealing enhancing directional response and higher temperatures leading to well-defined magnetocrystalline anisotropy. Structural analysis indicates a transition from predominantly L12 ordering in as-deposited and low-temperature annealed films to the emergence of the D03 phase at higher annealing temperatures, accompanied by lattice parameter variation and compositional redistribution. These results establish a direct correlation between annealing-induced phase transformation and magnetic anisotropy, providing insight into the controlled tuning of FeGa thin films for magnetostrictive and spintronic applications.
Superconductor/ferromagnet heterostructures provide a versatile platform for exploring spin-dependent superconducting phenomena arising from interfacial proximity effects. In this article, we investigate the structural and superconducting properties of Al thin films grown in situ by molecular beam epitaxy on strained F...

Two-dimensional (2D) van der Waals ferromagnets with strong perpendicular magnetic anisotropy and tunable magnetic stability are important for scaled spintronic devices. In this work, we investigate monolayer Fe3SiTe2 using first-principles calculations and atomistic Monte Carlo simulations, with emphasis on the effect...
Copper-doped zinc oxide (ZnO:Cu) thin films were deposited by vacuum thermal evaporation then annealed at 300°C, 400°C, and 500°C in order to tailor defect states and surface-related functional properties. X-ray diffraction analysis revealed a transition from an amorphous structure in the as-deposited film to a crystal...
