Abstract

Chemical synthesis is used for preparing the FePt nanoparticles with controlled composition. The difference in Curie temperature between the heating and cooling thermomagnetic curves of the Fe-Pt alloys is attributed to the difference of [alpha] [left right double arrow] [gamma] phase transition temperature during heating and cooling.
