Tuning morphology and magnetism in epitaxial L1_0-FePt films

In this work, well-ordered epitaxial FePt thin films have been grown by RF sputtering on two different substrates (MgO (100) and SrTiO3 (100)) and the effect of different lattice parameters between the substrate and FePt film on morphology and magnetic behavior has been considered. Growth conditions have been opti- mized to obtain different morphologies and magnetic behaviors.
