Electrically switching perpendicular magnetized ferromagnets using spin-orbit torques without assisting magnetic fields is a major goal for spintronics. Recently, several works have proposed using out-of-plane spin polarized currents to achieve this, but these rely on antiferromagnetic metals with low Neel temperatures. Here, Wang et al show that such out-of-plane spin polarization driven switching can be achieved using the interface of an antiferromagnetic insulator and a heavy metal.
