Fabrication and Characterization of Cobalt Ferrite (CoFe2O4) using Sonochemical Method for Promising Hyperthermia Sensor

Abstract

This research aimed to identify the effect of the sintering temperature on the morphology  and magnetic properties of CoFe2O4 using sonochemical methods. The prepared CoFe2O4 was  characterized by X-ray diffraction (XRD) for phase identification, scanning electron  microscope (SEM) for morphology, and magnetic properties using a vibrating sample magnetometer (VSM). Phase identification analysis showed that single phase CoFe2O4 with crystallite size of unsintered and sintered at 500, 600, and 700 oC were 24, 18, 21, and 27 nm,  respectively. In the morphological analysis, the sample showed a nanosphere and an  agglomerated form. The sample with the largest grain size was 34.11 nm sintered at 700 oC.  Saturation magnetization, remanent magnetization, and coercivity field had more substantial  values of 75.24 emu/g, 39.39 emu/g, and 0.198 T, respectively.
