Microstructure and magnetic property of nano-Fe particles prepared by hydrogen arc plasma

Nano-Fe magnetic particles were prepared by hydrogen arc 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...

Description
Summary:Nano-Fe magnetic particles were prepared by hydrogen arc 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 nanoparticles has an important effect on the magnetic properties. This method has potential application for producing nano-magnetic materials.
