Abstract
An apparatus comprises a write pole, a waveguide core, and a near-field transducer (NFT) positioned between the write pole and the waveguide core. The NFT comprises an enlarged portion and a peg comprising a refractory metal and extending from the enlarged portion toward a media-facing surface. A first dielectric layer is positioned between the peg and the write pole, and a first adhesion layer is positioned between the peg and the first dielectric layer. In addition, a second dielectric layer is disposed on an entire surface of the NFT opposing the media-facing surface, and a second adhesion layer is positioned between the NFT and the second dielectric layer.
