Abstract:
FePt alloy thin films of different thickness have been prepared and studied. Both X-ray analysis
and magnetization measurements have been used to detect the FCC (A1)-FCT (L10) phase transformation
due to annealing in these films. It was found that the ordering process in the thick samples takes place at
much lower temperature in comparison to the thinner ones. The observed phenomenon can be understood
taking into account the kinetics of the FCC-FCT phase transformation and grain growth. The obtained
experimental results suggest the existence of an optimal annealing temperature for each defined sample
thickness. ?? 2003 Elsevier B.V. All rights reserved.
