Abstract: A near-field transducer includes a substrate that defines a substrate-parallel plane. The near-field transducer also includes a composite layer deposited on the substrate-parallel plane. The composite layer has a first layer of the plasmonic material and a second layer of an insertion material adjacent the substrate. The insertion material reduces plastic deformation of the near-field transducer at elevated temperatures.

Abstract: A recording head includes a near-field transducer proximate a media-facing surface. The near-field transducer comprises an aperture portion surrounded by walls of plasmonic material, the walls oriented normal to the media-facing surface. A notch protrudes within the aperture. The notch comprises at least one of Rh and Ir. A write pole is proximate the near-field transducer. The write pole has a back surface facing away from the media-facing surface and an aperture-facing surface proximate the aperture.

Abstract: A near-field transducer includes first and second stacked base portions having a common outline shape. The second base portion is proximate alight delivery structure. A peg extends from the first base portion towards a media-facing surface. The peg includes a material that is more thermally robust than a plasmonic material of the base portion. The peg has a peg thickness that is less than a thickness of the first base portion. The first base portion has a first recess proximate the peg. The first recess separates the first base portion from the media-facing surface and exposes at least a top side of the peg.
