摘要：

This letter reports the results obtained by measuring the temperature dependence of the coercivity of magnetically isolated L1(0)-FePt nanoparticles in agglomeration-free films deposited by using a dispersion stabilizer and a spin-coat technique. These measurements not only give the basic magnetic parameters of the nanoparticles but also provide information about the nanoparticle ordering process. The temperature at which isolated FePt nanoparticles start to order seems to be about 650degreesC. (C) 2004 American Institute of Physics.
