Abstract

Thermally annealed superparamagnetic core shell nanoparticles of an iron-cobalt alloy core and a silicon dioxide shell having high magnetic saturation are provided. A magnetic core of high magnetic moment obtained by compression sintering the thermally annealed superparamagnetic core shell nanoparticles is also provided. The magnetic core has little core loss due to hysteresis or eddy current flow.
