Iron oxide and silica magnetic core
A magnetic core of superparamagnetic core shell nanoparticles having a particle size of less than 50 nm; wherein the core is an iron oxide and the shell is a silicon oxide is provided. The magnetic core is a monolithic structure of superparamagnetic core grains of iron oxide directly bonded by the silicon dioxide shells. A method to prepare the magnetic core which allows maintenance of the superparamagnetic state of the nanoparticles is also provided. The magnetic core has little core loss due to hysteresis or eddy current flow.
