摘要
Ag nanoparticles; with Fe3O4 shells have been synthesized by the polyol method. The Ag @ Fe3O4 core-shell nanoparticles exhibited a superparamagnetic behavior at the temperature higher than the blocking temperature (100 K) and showed shifted loops under a field cooling process. The enhanced magnetic anisotropy was observed and was ascribed to the surface effect.
