Abstract
A near-field transducer for an energy-assisted, magnetic recording head includes a first part comprising a first plasmonic material. The first part has an enlarged portion configured to receive optical energy from a waveguide and a narrowed portion that receives and channels the optical energy to a recording medium. The near-field transducer includes a second part comprising a nanorod of a second plasmonic material different than the first plasmonic material. The nanorod is disposed within the first part along a light propagation direction of the near-field transducer and extends to a media-facing surface of the recording head along a light propagation direction. The narrowed portion of the first part covers at least three sides of the nanorod along the light propagation direction. The nanorod has an exposed end that is exposed from the near-field transducer and faces the media-facing surface.
