Abstract:
According to one embodiment, a magnetic head includes a recording portion. The recording portion includes a magnetic pole, a shield, and a stacked body provided between the magnetic pole and the shield. The stacked body includes a first magnetic layer, a first layer provided between the first magnetic layer and the magnetic pole, and a first intermediate layer provided between the first magnetic layer and the shield. The first layer contacts the magnetic pole and includes at least one selected from the group consisting of IrMn, PtMn, FeMn, PdMn, NiMn, RhMn, MnCr, and PtCr. The first intermediate layer includes at least one selected from a first group consisting of Cu, Ag, Au, Al, Cr, and Ru.
