<p>PROBLEM TO BE SOLVED: To provide a microwave-assisted magnetic recording (MAMR) head with a highly resistive magnetic material.SOLUTION: In one embodiment, a high-frequency magnetic field-assisted magnetic recording (MAMR) head includes: a yoke adapted for facilitating magnetic flux through the MAMR head; a main pole magnetically coupled to the yoke and adapted for producing a writing magnetic field; a return pole separated from the main pole; a spin torque oscillator (STO) positioned above the main pole; and a back gap layer positioned between the yoke and the return pole. At least one of the yoke, the main pole, the return pole, and the back gap layer comprises a highly resistive magnetic material.</p> |
