Abstract: Devices having an air bearing surfaces (ABS), the devices including a near field transducer (NFT) that includes a disc having a front edge; a peg, the peg having a front surface at the air bearing surface of the apparatus, an opposing back surface, a top surface that extends from the front surface to the back surface, two side surfaces that expend from the front surface to the back surface and a bottom surface that extends from the front surface to the back surface; and a barrier layer, the barrier layer separating at least the back surface of the peg from the disc and the barrier layer having a thickness from 10 nm to 50 nm.
