    Abstract: According to one embodiment, an electromagnetic wave attenuator includes a multilayer member, and a magnetic member. The multilayer member includes a plurality of magnetic layers and a plurality of nonmagnetic layers. The plurality of nonmagnetic layers is conductive. A direction from one of the plurality of magnetic layers toward an other one of the plurality of magnetic layers is aligned with a first direction from the multilayer member toward the magnetic member. One of the plurality of nonmagnetic layers is between the one of the plurality of magnetic layers and the other one of the plurality of magnetic layers. A thickness along the first direction of the magnetic member is not less than ½ of a thickness along the first direction of the multilayer member.

    Abstract: According to one embodiment, a magnetic recording head includes an air bearing surface, a magnetic pole having a distal end portion, a write shield opposed to the distal end portion of the magnetic pole across a write gap, and a high-frequency oscillator between the magnetic pole and the write shield in the write gap. The high-frequency oscillator includes a spin injection layer, an intermediate layer and an oscillation layer which are stacked in a head travel direction. A film thickness of the spin injection layer in the head travel direction at a height position away from the air bearing surface is greater than a film thickness of the spin injection layer in the head travel direction on the air bearing surface.
