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.
