A heat-assisted magnetic recording head comprises a near-field transducer (NFT). The NFT comprises a near-field emitter configured to heat a surface of a magnetic disk, and a hybrid plasmonic disk. The hybrid plasmonic disk comprises a plasmonic region and a thermal region. The plasmonic region comprises a first material or alloy that is a plasmonic material or alloy. The thermal region comprises a second material or alloy that is different than the first material or alloy.
