The (FeCo)3Pt thin films grown on MgO(100) and Al2O3(00∙1) substrates are found to be fcc with <100> and <111> orientations, respectively. Based on these orientations, they show fourfold and sixfold anisotropy in the in-plane. The <100> oriented film shows in-plane fourfold anisotropy of the order of 105 erg/cc. On the other hand, the film grown on Al2O3(00∙1) exhibits large basal plane sixfold magnetic anisotropy (∼106 erg/cc) and is strongly dependent on deposition temperature. © 2004 American Institute of Physics.
