Abstract
Devices that include a near field transducer (NFT), the NFT having at least one external surface; and at least one adhesion layer positioned on at least a portion of the at least one external surface, the adhesion layer including oxides of yttrium, oxides of scandium, oxides of lanthanoids, oxides of actionoids, oxides of zinc, or combinations thereof.
Claims19
A device comprising:
- a near field transducer (NFT), the NFT having at least one external surface;
- and
- at least one adhesion layer positioned on at least a portion of the at least one external surface, the adhesion layer comprising oxides of scandium, oxides of lanthanoids, oxides of actinoids, or combinations thereof, and the at least one adhesion layer having an average thickness from 1 nanometer (nm) to 10 nm.
A device comprising:
- a near field transducer (NFT), the NFT comprising a disc and a peg, wherein the peg has five surfaces thereof and the disc has an upper surface and a side surface;
- and
- at least one adhesion layer positioned on at least one surface of the peg or the disc, the adhesion layer comprising oxides of scandium, oxides of lanthanoids, oxides of actinoids, or combinations thereof, the at least one adhesion layer having an average thickness from 1 nanometer (nm) to 10 nm.
A device comprising:
- an energy source;
- a near field transducer (NFT) configured to receive energy from the energy source, the NFT having at least one external surface;
- and
- at least one adhesion layer positioned on at least a portion of the at least one external surface, the adhesion layer comprising oxides of scandium, oxides of lanthanoids, oxides of actionoids, or combinations thereof, the at least one adhesion layer having an average thickness from 1 nanometer (nm) to 10 nm.
