Abstract:
The present invention relates to a core-shell structured nanoparticle having hard-soft heterostructure, magnet prepared from the nanoparticle, and preparing method thereof. The core-shell structured nanoparticle having hard-soft magnetic heterostructure of present invention has some merits such as independence from resource supply problem of rare earth elements and low price and can overcome physical and magnetic limitations possessed by the conventional ferrite mono-phased material.
