Synthesis and property of core-shell Ag@Fe/sub 3/O/sub 4/ nanoparticles

Abstract

Ag nanoparticles with Fe/sub 3/O/sub 4/ shells have been synthesized by the polyol method. The Ag@Fe/sub 3/O/sub 4/ 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… (More)
