Nano-Fe magnetic particles were prepared by hydrogen are plasma method and
post annealing process. The microstructures and magnetic properties of the
particles were studied by TEM, XRD and vibration magnetometer. It was found
that the post annealing and formed shell-core structure of the nanoparticl
es has an important effect on the magnetic properties. This method has pote
ntial application for producing nano-magnetic materials. (C) 2000 Elsevier
