Abstract It is shown that the crystallization of the sputtered amorphous Sin-Co magnetic films is entirely different from that of the thicker plasma-sprayed ones given in literature. On heating the sputtered amorphous films, a β-Co transition metal phase forms first, no rare earth-transition intermetallic compound was observed till 750℃. This is believed to be related to the higher surface energy of thin films.
