Ultrafast magnetization enhancement and spin current injection in magnetic multilayers by exciting the nonmagnetic metal

Autor: Lu, Wen-Tian, Yuan, Zhe, Xu, Xiaohong

A systematic investigation of spin injection behavior in Au/FM (FM = Fe and Ni) multilayers is performed using the superdiffusive spin transport theory. By exciting the nonmagnetic layer, the laser-induced hot electrons may transfer spin angular mome
