Efforts to improve the spin–orbit torque efficiencies in junctions consisting of nonmagnetic and ferromagnetic layers are current technological interest to construct magnetic memory and logic devices. However, most of the previous studies have relied on pure metallic elements, and thus, the outcomes...
