“…For the CCMF sample a closer investigation into the HR-TEM image shows the presence of two types of crystallites that can be well correlated to the XRD observations. The high value of lattice micro-strain of the materials can be best explained on the basis of charge carrier hopping between Fe 2+ ↔Fe 3+ , Co 2+ ↔Co 3+ , Cu 2+ ↔Cu 3+ and Mo 2+ ↔Mo 3+ ions, so that the electric dipoles align themselves along the applied alternating eld [24].

In the current research, Cu0.5Co0.3Mo0.2Fe2O4 mixed ferrite nanoparticles have been synthesized using Co-precipitation method. XRD patterns show the development of polyphasic copper, cobalt and molybdenum mixed spinel composition. The particle size of ferrite system is 16nm and they are nanoparticles. The lattice constant was determined to be 8.368 Å used for the highest peak (311). FTIR spectroscopy shows the lower octahedral and higher tetrahedral frequency alignment of ions in the spinel ferrite leading to the octahedral 550 cm− 1 and the tetrahedral 471 cm− 1 vibration modes. TEM micrographs showed spherical morphology and their particle size less than 50 nm, which correlated XRD crystallite size. VSM shows excellent ferrimagnetic properties because of higher coercivity (985.29 G). These higher coercivity materials can make cathode content for Li-ion batteries.
