The magneto-optical Kerr rotation (θK) spectra and the related properties have been measured in ordered and disordered phases of several kinds of Fe-Pt alloy films. The |θK| in as-deposited (disordered) films becomes gradually larger with increasing Fe content until about 50 at% Fe, but the shape of θK spectra does not change so much. After annealing, however, all the θK spectra were changed. A considerable change of the θK spectra near 300 nm, which would be expected by the anti-parallel alighment of the polarized Pt spins to Fe spins after annealing, was not observed in the films with approx. 50 at% Fe.
