Abstract:
An apparatus includes a polarizer, a first free layer, a second free layer, and an antiferromagnetic (AF) coupling layer. The polarizer has a perpendicular magnetic anisotropy (PMA). The polarizer, the first free layer, the second free layer, and the AF coupling layer are included in a spin-torque oscillator (STO). The AF coupling layer is positioned between the first free layer and the second free layer.
