A systematic study of the magnetic and structural properties of Fe_3Pt alloy thin films has been carried out. It is realized that the orientation of the Fe_3Pt thin films can be controlled by choosing the different oriented substrate. The Fe_3Pt 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, K_1 and K_2 of Fe_3Pt films are obtained about -4×l0^6 and 2×10^7 erg/cc respectively, which are the new findings ever found for Fe_3Pt films. A close relationship is observed between the magnetic anisotropy constants and structural parameter. The magneto-optical properties of Fe_3Pt thin films are found similar to the bulk that is attributed to strong hybridization.
