 Abstract:

The sample of CoFe2O4 magnetic nanoparticles (MNPs) is synthesized via co-precipitation method from ferrous and ferric solutions. Transmission Electron Microscopy (TEM) and X-ray diffraction (XRD) were used to characterize the powder synthesized from the sample. The average lattice parameter and the average size of CoFe2O4 were a = 8.4 Å and t = 13 nm. The magnetization measurements of CoFe2O4 at room temperature up to a maximum magnetic field (H) of 9000 (Oe) by using vibrating sample magnetometer (VSM) homemade and saturation magnetization (Ms = 48 emu/g), remanent magnetization (Mr = 10.8emu/g) and coercive force (Hc = 240 Oe) were evaluated. Induction heater operated at low frequencies 100 kHz was used to study the thermal properties of the CoFe2O4. The results shown; the maximum temperature (T = 59 oC), the heating rate (DT/Dt = 0.027 oC/sec) and the specific absorption rate (SAR = 224 W/g).
