1. A magnetic recording head, comprising:
a main pole having a first surface disposed at a gas-bearing surface (GBS), a second surface perpendicular to the first surface, and a third surface disposed between the first surface and the second surface, the third surface being parallel to the first surface;
a near-field transducer (NFT) disposed adjacent to the second surface of the main pole, the NFT having an output tip disposed at the GBS;
a thermal shunt disposed between the NFT and the second surface of the main pole, the thermal shunt being recessed from the GBS; and
a plasmonic material disposed between the first surface of the main pole and the output tip of the NFT, the plasmonic material extending from the GBS to the third surface of the main pole.
