摘要
Core shell nanoparticles of an iron oxide core, a silicon dioxide shell and an iron silicate interface between the core and the shell are provided. The magnetic properties of the nanoparticles are tunable by control of the iron silicate interface thickness. 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.
