- - Core-Shell Structured Nanoparticle having Hard-soft Magnetic Heterostructure Magnet Prepared with Said Nanoparticle and Preparing Method thereof

摘要

The present invention is a core-relates to a magnet, and methods for their preparation prepared using the nanoparticles, the nanoparticles of a soft magnetic hybrid structure - gyeong having a shell structure. If the present invention soft magnetic nanoparticles in the hybrid structures may overcome the limitations of the physical and magnetic properties with the free and low price advantage ever the daily traditional hard magnetic material only from the rare earth resource supply and demand issues.;
