  • Methods of forming portions of near field transducers (NFTS) and articles formed thereby
    Patent number: 10424324
    Abstract: Methods that include forming at least a portion of a near field transducer (NFT) structure; depositing a material onto at least one surface of the portion of the NFT to form a metal containing layer; and subjecting the metal containing layer to conditions that cause diffusion of at least a portion of the material into the at least one surface of the portion of the NFT; and devices formed thereby.
    Type: Grant
    Filed: December 11, 2017
    Date of Patent: September 24, 2019

  • Magnetic devices including film structures
    Patent number: 9679590
    Abstract: A device including a magnetic structure, the magnetic structure having a substrate adjacent surface and a second, opposing surface, the magnetic structure having a near field transducer (NFT), wherein the NFT includes gold or an alloy thereof, and is positioned at the second surface an overcoat structure; and a film structure, the film structure positioned between the magnetic structure and the overcoat structure, the film structure having a total thickness of not greater than about 100 ?, and the film structure including: a first interfacial structure having a first and a second opposing surface; a second interfacial structure having a first and a second opposing surface; and an intermediate structure wherein the first surface of the first interfacial structure is positioned adjacent the NFT of the magnetic structure, and the second surface of the second interfacial structure is positioned adjacent the overcoat structure, and the intermediate structure is positioned between the first interfacial structure an
