Abstract: Methods of forming a near field transducer (NFT), the methods including the steps of depositing plasmonic material on a substrate; laser annealing at least a portion of the deposited plasmonic material at a wavelength from 100 nm to 2.0 micrometers (μm) to induce liquid phase epitaxy (LPE) in the annealed deposited plasmonic material to form a epitaxially modified plasmonic material; and forming a NFT from at least a portion of the epitaxially modified plasmonic material are disclosed as well as other methods and devices such as those formed.
