摘要：
A general strategy for the synthesis of high chemically ordered L1(0) alloy nanoparticles is presented. L1(0) FePt nanoparticles are obtained directly from the atomically layered precursor FePtCl6 center dot 6H(2)O. The method is easy and low cost, and the FePt nanoparticles, obtained at 400 degrees C, present a very high magnetic anisotropy.
