Template Growth for Uniform Grain Size Distribution

Objective: Develop Fabrication Method for Grain w/ Uniform Size Distribution
Feature: Using self-assembled Au nanoparticles to create a template for FePt media

3nm Au nanoparticles are self-assembled on protected MgOunderlayer followed by deposition of a thin layer of adequate grain boundary material. Au nanoparticles are, then, selectively etched away, leaving cavities formed by the grain boundary material. Sputtered FePtat elevated temperature will epitaxial grow on the MgOunderlayer at the bottom of the cavities, creating microstructure conforming to the self-assembled Au particles.
