The potent core : A new approach to preparing highly magnetic nanoparticles consisting of a ferromagnetic core (Fe) and an artificial ferrite shell was developed. The monometallic core contributes to high overall magnetization. The superparamagnetic ferrite shell protects the core against oxidation and further increases magnetization while minimizing particle aggregation.
