Description

The spin-torque oscillator (STO) is the most important component in microwave-assisted magnetic recording (MAMR). Some requirements for the STO are: large amplitude and stable oscillation, small injected current and oscillation at a frequency that excites resonance in a recording medium. It is also necessary for the STO oscillation to closely follow the head coil current. In this paper, STOs were integrated into write heads and micromagnetic analyses carried out to obtain a write head structure with stable STO oscillation that could follow a high frequency head coil current. STO materials were also investigated for small injected currents.
