Abstract

A magnetic system containing a plurality of stacked layer arrays, each of which includes a first anti-ferromagnetic (AFM1) layer, a heavy metal (HM) layer formed of a material having strong spin-orbit coupling, and, optionally, a ferromagnetic (FM) layer or a second anti-ferromagnetic (AFM2) layer. Also disclosed is a method of preparing such a magnetic system.
