Growth and characterization of epitaxial FePt films

The magnetic and structural properties of Fe53Pt47 deposited by alternated-layer sputtering on MgO (100), heated at temperatures up to T=550 °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.
