英文摘要	This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications. The best is to read these instructions and follow the outline of this text. FePt nanoparticles with spherical shapes were prepared by reduction of Fe(acac)(3) (acac = acetylacetonate) and H2PtCl6 center dot 6H(2)O in the presence of surfactant poly(N-vinyl-2-pyrrolidone) (PVP). XRD, TEM and VSM results confirm that the PVP contents affect rarely the morphology and crystal structure of FePt nanoparticles, while result in a big change of their magnetic properties. The highest coercivity up to 5.2 kOe was obtained at PVP / FePt molar ratio of 7.0.
