Description

Pulsed laser deposition from elemental targets was used to prepare L10 ordered Fe-Pt films directly on heated MgO(100) substrates. The influence of composition on the c-axis lattice parameter, microstructure and coercivity is examined. Strong (001) texture and maximum coercivities above 5T were observed for slightly Pt-rich compositions. When Fe droplets are produced during the ablation process, an additional phase without hard magnetic properties is formed. A comparison of the surface composition to the lattice parameter within the film indicates Pt segregation to the surface during film growth, consistent with a full termination of the surface by Pt
