- Abstract
- It was studied that FePt-Ta thin films prepared on MgO (1 0 0) buffer-layer by DC/RF magnetron co-sputtering have shown better magnetic properties and micro structural improvement. The Ta-doped FePt-Ta films indicate somewhat differences in micro structural ordering and the aspect of grain growth after annealing. With respect to magnetic property, the sample having 30% increased coercivity was obtained after a heat treatment at 700 degrees C. In particular the addition of Ta (5.5%) enhances the L1(0) ordering of FePt at relatively high temperature (above 500 degrees C). (C) 2010 Elsevier B.V. All rights reserved.
