Abstract
Enhanced magnetic moment is induced in nonmagnetic metals. Specifically, gold, silver, and copper are rendered with bulk magnetic behavior by doping these metals with ferrimagnetic strontium hexa-ferrite (SrFe12O19) nanoparticles. The doped metals exhibit classical macroscopic permanent magnetic properties. Remarkably, detailed magnetization studies reveal that the saturation moments (MS) of these materials are enhanced by a factor of 5-8 compared to pure SrFe12O19 nanoparticles. The enhancement order is Cu>Ag>Au. A mechanism is suggested for the enhancement and for its order, based on a full materials characterization of these SrFe12O19@Metals.
