摘要：

High temperature solution phase decomposition of Fe(CO)(5) and reduction of Pt(acac)(2) in the presence of stabilizers of oleic acid and oleyl amine are employed to produce Fel(1-x)Pt(x) alloy nanoparticles. The Fe and Pt composition of the nanosized materials can be tuned by adjusting the molar ratio of Fe(CO)(5) to Pt(acac)(2), and the compositions ranging from Fe40Pt60 to Fe80Pt20 are obtained. This study is to investigate the influence of the composition on Curie temperature (T-c) of Fe1-xPtx nanoparticles monitored by thermomagnetic analysis (TMA).
