Abstract
Recently much interest has been aroused by L10 ordered FePt thin films due to their large magnetocrystalline anisotropy, which is required for ultra-high-density magnetic recording media. The grain size of pure FePt films is fairly large, which can cause medium noise and a reduction of recording resolution. We prepared FePt and FePt-Al2O3 films by the in-situ ordering method, aiming to suppress the growth of grain size by transforming the disordered fcc phase into the L10 structure.
