In this paper, a simple sol-gel combined hydrogen reduction synthesis of FeNi3/SiO2 core-shell nanoparticles was reported. The real part mu' of the permeability for FeNi3/SiO2 nanoparticles does not decrease in the frequency range measured, even up to at least 1 GHz, simultaneously, the loss of mu is very small. Our method provides a promising route to achieve soft magnetic material with good magnetic properties, especially in the high-frequency range. (C) 2004 Elsevier Ltd. All rights reserved.
