摘要：

The amine functionalized CoFe2O4 nanoparticles were prepared by thermal decomposition method at reflux temperatures 160 degrees C and 172 degrees C. The obtained CoFe2O4 nanoparticles at 160 degrees C reflux temperature show aggregation free poly-dispersed nanoparticles in 4-15 nm range. In an elevated reflux temperature of 172 degrees C, CoFe2O4 show aggregated poly-dispersed nanoparticles in the size range of 20-46 nm. The saturation magnetization value at 300 K exhibited 51 emu/g at reflux temperature of 160 degrees C. However, the sample synthesized at an elevated temperature of 172 degrees C has shown a coercive field value of 560 Oe with saturation magnetization of 68 emu/g.
