Abstract

Abstract2D layered materials with broken inversion symmetry are being extensively pursued as spin source 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, the experimental observation of spin–orbit torque magnetization self‐switching at room temperature in a layered polar ferromagnetic metal, Fe2.5Co2.5GeTe2 is reported. The spin–orbit torque is generated from the broken inversion symmetry along the c‐axis of the crystal. These results provide a direct pathway toward applicable 2D spintronic devices.
