Effects of third elements (Ag, B, Cu, Ir) addition and high Ar gas pressure on L10 FePt films

To obtain lower disorder/order transformation temperature of L1(0) FePt alloy films, we prepared the films with adding the third elements (Ag, Cu, B, Ir) and under high Ar gas pressure. It was found the temperature decreases from 500degreesC to 400degreesC by adding all of third elements and by preparing under high Ar gas pressure of 250 m Torr. (C) 2003 Elsevier B.V.
