L10-ordered high coercivity (FePt)Ag–C granular thin films for perpendicular recording

We report (FePt)Ag–C granular thin films for potential applications to ultrahigh density perpendicular recording media, that were processed by co-sputtering FePt, Ag, and C targets on MgO underlayer deposited on thermally oxidized Si substrates. (FePt)1−xAgx–yvol%C (0
