Nickel ferrite nanoparticles with copper atoms as dopant have been prepared using co-precipitation method with general formula Ni 1-x Cu x Fe 2 O 4 (x=0.2, 0.4, 0.6, 0.8 and 1) and are sintered at quite ambient temperature. Structural and magnetic properties were examined using Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction method (XRD) and Vibrating Sample Magnetometer (VSM) to study the influence of copper doping in nickel ferrite magnetic nanoparticles. X-ray studies proves that the particles are possessing single phase spinel structure with an average particle size calculated using Debye Scherer formula. Magnetic measurements reveal that saturation magnetization value (M s ) decreases while magnetic coercivity (H c ) increases upon doping.
