Differential scanning calorimetry studies of the effect of Cu on the A1 to L10 transformation in FePt thin films

Differential scanning calorimetry studies of the effect of Cu on the A1 to L10 transformation in FePt thin films

Ternary FeCuPt alloys with 1-5 at.% Cu produced no advantage over equivalent binary FePt alloys in terms of lowering the kinetic ordering temperature. The Curie temperature decreased with increasing Cu content. The transformation enthalpy and activation energy were not affected.
