Switching of a single ferromagnetic layer driven by spin Hall effect

Torna indietro

Abstract

The magnetization switching of a thin ferromagnetic layer placed on top of a heavy metal (such as Pt, Ta, or W) driven by an in-plane current has been observed in recent experiments. The magnetization dynamics of these processes is studied in a full micromagnetic framework which takes into account the transfer-torque from spin Hall effect due to the spin-orbit coupling. Simulations indicate that the reversal occurs via nucleation of complex magnetization patterns. In particular, magnetic bubbles appear during the reversal of the magnetization in the perpendicular configuration while for the in-plane configuration, nucleation of vortexes is observed.
