Growth and characterization of epitaxial Fe-Pt films

The magnetic and structural properties of Fe/sub 53/Pt/sub 47/ deposited by alternated-layer sputtering on MgO (100), heated at temperatures up to T=550/spl deg/C, were investigated. The effect of a subsequent thermal annealing performed at the same temperature was found to be essential for obtaining 10-nm FePt thin films with a high degree of ordering and high squareness.
