Effects of annealing on the structural, morphological and magnetic properties of CuFe2O4 Ferrite Nanoparticles synthesized by chemical precipitation

Magnetic ferrite nanoparticles have been employed by co-precipitation method. XRD diffraction patterns have confirmed ferrite spinel BCC crystal structure. FTIR spectra were recorded between of 400 cm−1 and 4000 cm−1 and explain inverse spinal structure have lower and higher frequency modes. At 1000 °C, the maximum band energy gab value is 1.85 eV. FE-SEM micrographs explain the irregular shape morphology magnetic nanoparticles with much porosity. VSM reveal single domain nanoparticles with ferrimagnetic behavior. Copper ferrite nanoparticles are proposed as a low-cost, no toxicity. The rammance ratio of tunable CuFe2O4 is lower (0.053 to 0.116), which is functionalized for sensor applications.
