Magnetization dynamics in spin-torque oscillator with negative Ku for microwave assisted magnetic recording

The paper discusses the magnetization dynamics of spin-torque oscillator with negative Ku under alternative head field for microwave assisted magnetic recording. Magnetization switching of spin-injection layer (SIL) is essential to have the same precession mode of the field generation layer before and after the head field change directions. The SIL needs to… CONTINUE READING
