Ultrafast magnetization enhancement in metallic multilayers driven by superdiffusive spin current (original) (raw)

This research investigates the ultrafast magnetization dynamics in metallic multilayers induced by superdiffusive spin currents. Employing a combination of experimentation and theoretical modeling, the study demonstrates how laser-induced demagnetization in one layer can lead to enhanced magnetization in another layer through superdiffusive spin transport mechanisms. The findings have significant implications for future spintronic applications, particularly in reducing energy dissipation in nanoelectronics.
