چکیده

In this study we report on the synthesis and characterization of cobalt ferrite (CoFe2O4) nanoparticles (NPs), synthesized by chemical co-precipitation in alkaline medium. Two samples were at two different temperatures, 35 90 oC. Both characterized Transmission Electron Microscopy (TEM), x-ray diffraction (XRD), room-temperature (RT) magnetization. showed superparamagnetic behavior (SPM) RT. TEM reveals morphological mean diameter increasing 5.8 nm to 10.4 nm, with increase temperature. XRD confirm inverse cubic spinel structure. The RT magnetization curves analyzed first-order Langevin function averaged out a lognormal distribution magnetic moments. This analysis saturation moment increases from 60.2 74.8 emu/g 3.9 x 103 8.2 mB, respectively.
