Claims21
A device having an air bearing surface (ABS), the device comprising:
- a write pole;
- a near field transducer (NFT) comprising a peg and a disc, wherein the peg is at the ABS of the device;
- a metallic layer positioned over at least the peg of the NFT at the ABS, the metallic layer comprising:
- iridium (Ir), rhodium (Rh), ruthenium (Ru), radium (Ra)—is this correct?, platinum (Pt), palladium (Pd), rhenium (Re), chromium (Cr), niobium (Nb), nickel (Ni), lead (Pb), silicon (Si), tin (Sn), aluminum (Al), tungsten (W), molybdenum (Mo), hafnium (Hf), titanium (Ti), zirconium (Zr), yttrium (Y), or combinations thereof;
- and
- an overcoat positioned over at least the metallic layer.
