Abstract
An apparatus includes a writer, an arrangement comprising a plasmonic near-field transducer (NFT) adjacent the writer and comprising a material having a temperature coefficient of resistance (TCR), and a lead arrangement connected to the NFT arrangement. In some configurations, the NFT arrangement includes a heat sink, and the lead arrangement is connected to the heat sink. In other configurations, the lead arrangement is connected directly to the NFT.
