Abstract
A systematic study of the magnetic and structuralproperties of Fe3Pt alloy thin films has been carried out. It is realized that the orientation of the Fe3Pt thin films can be controlled by choosing the different oriented substrate. The Fe3Pt thin films are found to exhibit very large in-plane magnetic anisotropy. By changing the deposition temperature, one can tune the magnetic anisotropy constants of the films. The maximum value of magnetic anisotropy constants, K1 and K2 of Fe3Pt films are obtained about -4×106 and 2×107erg/cc respectively, which are the new findings ever found for Fe3Pt films. A close relationship is observed between the magnetic anisotropy constants and structural parameter. The magneto-optical properties of Fe3Pt thin films are found similar to the bulk that is attributed to strong hybridization.
