The additions of Au and Ag to FePt thin film change the film structure from an interconnected network to a completely isolated island structure. In particular, the Ag addition led to an isolated particulate structure smaller than 100 nm, which increased the coercivity from 5.4 to 20.5 kOe. Energy filtered elemental mapping did not show evidence for the precipitation or segregation of Au and Ag.
