- Abstract
Chemically mixed Mn1-xCoxFe2O4 nanoparticles with the size about 8 nm were synthesized by thermal decomposition method. The content of Co element x varied from 0.02 to 0.08. Magnetic measurement indicated that 8 nm Mn1-xCoxFe2O4 nanoparticles were superparamagnetic at room temperature and ferromagnetic at the temperature of 5 K. Both the blocking temperature and coercivity of Mn1-xCoxFe2O4 nanoparticles increased with increasing Co addition. Mn1-xCoxFe2O4 nanoparticles showed not only high saturated magnetization but also large coercivity at low temperature, which have great potential in magnetic nanodevice and biomagnetic applications.
