Abstract
Two-dimensional layered materials with broken inversion symmetry are being extensively pursued as spin-orbit coupling layers to realize high-efficiency magnetic switching. Such low-symmetry layered systems are, however, scarce. In addition, most layered magnets with perpendicular magnetic anisotropy show a low Curie temperature. Here, we report the experimental observation of spin-orbit torque magnetization self-switching at room temperature in a layered polar ferromagnetic metal, Fe2.5 Co2.5 GeTe2 . The spin-orbit torque is generated from the broken inversion symmetry along the c axis of the crystal. Our results provide a direct pathway toward applicable two-dimensional spintronic devices.
