Synthesis of nanosized MgFe_2O_4 powders by microwave hydrothermal method

摘要

Nanosized magnesium ferrite, MgFe_2O_4, is synthesized under mild microwave hydrothermal (MH) conditions. Powder X-ray diffraction and transmission electron microscopic studies showed that the average particle size of the ferrite obtained is approx 3 nm, with a narrow size distribution. Vibrating sample magnetometric studies showed the existence of superparamagnetic state of the ferrite particles.
