摘要
The magnetic moments of disordered and ordered L1 0 Fe 50 Pt 50 films were investigated using magnetic circular dichroism (MCD) and spin polarized full relativistic Korringa-Kohn-Rostoker (SPRKKR) calculations. The measurements showed that the spin magnetic moments of Fe in both ordered and disordered films were similar with a lower value than that obtained by SPRKKR calculations. Both films however showed larger orbital moments of Fe compared to the calculations. It is suggested that the spin magnetic moment of Fe in FePt thin films was insensitive to L1 0 ordering. © 2006 The Japan Society of Applied Physics.
