Synthesis of nanosized MgFe2O4 powders by microwave hydrothermal method

Nanosized magnesium ferrite, MgFe2O4, was synthesised under mild microwave hydrothermal conditions (150 C; 50 psi, 25 min). Powder XRD and TEM studies showed that the average particle size of the ferrite obtained is about 3 nm, with a narrow size distribution. Vibrating sample magnetometric studies...

description Nanosized magnesium ferrite, MgFe2O4, was synthesised under mild microwave hydrothermal conditions (150 C; 50 psi, 25 min). Powder XRD and TEM studies showed that the average particle size of the ferrite obtained is about 3 nm, with a narrow size distribution. Vibrating sample magnetometric studies showed the existence of the superparamagnetic state in the ferrite particles above the blocking temperature of 38 K. 25 refs.
