Summary, etc. <strong>The copper based CuFe<sub>2</sub>O<sub>4 </sub>nanoferrite<sub> </sub>was prepared by chemical co-precipitation method and the detailed investigation of structural and magnetic properties was carried out successfully at room temperature. The obtained results from XRD confirm that CuFe<sub>2</sub>O<sub>4 </sub>has tetragonal structure at room temperature and its crystallite size, lattice strain was found to be varied from 11 to 17 nm and 3.910<sup>-2</sup> to 2.610<sup>-2</sup> for microwave annealed to as-prepared samples calculated using Scherrer equation and Williamson-Hall analysis, respectively. A clear superparamagnetic behaviour was observed in as-prepared and hot air oven annealed nanoferrite samples at RT under the field range of ±2 T. A distorted superparamagnetic curve was determined from isothermal magnetic hysteresis studies for the microwave oven annealed sample. It might be a possible magnetic and non-magnetic cation transformation on the surface of CuFe<sub>2</sub>O<sub>4 </sub>nanoparticles along with high lattice strain resulting in change of magnetic properties under certain level of applied magnetic field.</strong>
