Nanosized CoxNi1−xFe2O4 powders were prepared in ethylene glycol solution under mild temperature and pressure conditions by precipitation from metal nitrates. The average size and distribution of the synthesized CoxNi1−xFe2O4 powders was about 15 nm and narrow, respectively. The magnetic property of the synthesized CoxNi1−xFe2O4 powder was about 60 (emu/g) with superparamagnetic character at room temperature.
