Abstract

Read online

Spin-orbit torques driven by the conventional spin Hall effect are widely used to switch magnetization, but this approach is nondeterministic and inefficient for magnets with perpendicular magnetic anisotropy. Here, the authors demonstrate deterministic, field-free switching in a Ni/Co multilayer by exploiting the magnetic spin Hall effect in adjacent Mn3Sn.
