报告内容： 

By applying newly developed “salt-matrix annealing” and “surfactant-assisted milling” techniques, monodisperse ferromagnetic FePt, FeCo, SmCo and NdFeB nanoparticles have been successfully synthesized. These first-ever-available nanoparticles display various hard and soft magnetic properties at room temperature with size dependent properties. The ferromagnetic nanoparticles are used as building blocks for advanced bulk and thin film magnets, and can be also applied in biomedical technologies and magnetic recording media.
