- Abstract
- FePt thin films were epitaxially grown by RF sputtering on MgO ( 1 0 0) substrates at 550 degrees C, followed by in situ annealing at the same temperature. The in situ annealing was found to improve the magnetic characteristics: i.e., the increase in magnetic squareness up to 0.9 and increase in the ratio between anisotropy and coercivity (epsilon = anisotropy field/coercive field = 35.9 for 115 min annealing). Remarkably, a decrease in grain size was also found to occur by increasing the annealing time. (c) 2007 Elsevier B.V. All rights reserved. (literal)
