Abstract

The structural properties and magnetic phase stability of [Fe.sub.(x)][Pt.sub.(1-x)] alloys in [L1.sub.2] crystal structure in bulk as well as thin film on Pt (110) substrate are analyzed by using highly precise full-potential linearized augmented plane-wave method within generalized gradient approximation. The ferromagnetic (FM) preference of thin film is predicted to fast suppress as the film thickness has increased and the antiferromagnetic (AFM) preference is recovered for the film thickness of five atomic layers.
