    摘要: An apparatus includes a recording media including a substrate, a plurality of tracks of magnetic material on the substrate, and a non-magnetic material between the tracks; a recording head having an air bearing surface positioned adjacent to the recording media, and including a magnetic pole, an optical transducer, and a near-field transducer, wherein the near-field transducer directs electromagnetic radiation onto tracks to heat portions of the tracks and a magnetic field from the magnetic pole is used to create magnetic transitions in the heated portions of the tracks; and a plasmonic material positioned adjacent to the magnetic material to increase coupling between the electromagnetic radiation and the magnetic material.

    摘要: A multilayer structure and method for making the same. In accordance with some embodiments, a multilayer structure has a first layer of Fe, a layer of A1 phase FePt on the first layer of Fe, and a second layer o Fe on the layer of FePt. The multilayer structure is annealed to convert the A1 phase FePt to L1o phase FePt.
