摘要
Ordered faced-centered tetragonal (fct) FePt nanoparticles were successfully synthesized by a chemical method using presynthesized Au nanoparticles as the "catalyst." The reaction temperature was also studied and it seems that there is an optimum value of 360 degrees C where the fct structure is formed. The particles have a mean diameter of 3.5-15 nm and the x-ray diffraction patterns exhibited (001) and (110), which signified the tetragonal phase formation. Room temperature magnetic hysteresis loops show that the FePt particles have coercive fields between 0.68 and 2.8 kOe. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3559484]
