Magnetic Order and Coupling Phenomena

Recent advancements in magnetic coupling phenomena are explored, focusing on ferrimagnetic rare-earth transition-metal Tb-Fe alloys and their heterostructures. The research highlights how the exchange coupling can be finely tuned through variations in the stoichiometry of the Tb-Fe layer, the repetition of Co/Pt multilayers, and the thickness of interlayer spacers. These modifications lead to significant perpendicular unidirectional anisotropy at room temperature, paving the way for innovative applications in the field of spintronics.
