Abstract
The present embodiments relate to a pre-assisted microwave assisted magnetic recording (PA-MAMR) write head that utilizes spin-Hall nano-oscillators (SHNOs). The SHNO can include a free layer and a spin-hall layer comprising a spin-hall material(s). The SHNO(s) can be disposed in a leading shield (LS) region and can be used to pump energy into the media before the writing process. A spin-torque oscillator (STO) utilized in other write head designs can be replaced with SHNOs, which can pre-excite the media and let the media oscillation damp over time and then switch under the writer field.
