Pulsed laser deposition and ordering of thin FePt films — •André Holz, Christian Lange, and Peter Schaaf — Universität Göttingen, II. Physikalisches Institut, Friedrich-Hund-Platz 1, 37077 Göttingen, Germany
Thin FePt-multilayer films with different film-thicknesses of the individual layers (0.5 nm - 10 nm) have been produced on MgO(100)-substrates by Pulsed Laser Deposition (PLD) with an Excimer laser. Annealing at different temperatures, ion-beam implantation with Xenon and ion-beam assisted deposition with Argon-ions for increased mobility on the substrate have been used in order to obtain an ordered FePt film with L10 structure and to study the necessary ordering effects. The films were examined by XRD, RBS, MOKE, Mössbauer spectroscopy, MOMS and SEM. Texturing effects and magnetic anisotropy were observed.
