Zn-substituted Cu-Ni ferrite nanoparticles ZnxCu0.5-xNi0.5Fe2O4, (where 0 = x = 0.5 with interval 0.1) have been synthesized using co-precipitation method which have been sintered at 900°C for 3 h. The X-ray diffraction (XRD) technique has been employed to confirm the single phase formation of spinel ferrite structure. The average particle size has been found in the range of 14-28 nm which has been estimated using Scherer's formula. The morphology of synthesized particle size has been confirmed using scanning electron microscopy (SEM). The size of particles has been found in close agreement with the XRD analysis. The optical band gap energy has been measured for x = 0.5 which have been found 2.3 eV. Moreover, the magnetic properties of sample x = 0.00 have also been observed. The saturation magnetization (Ms), remanance, Mr/Ms and coercive force have been observed. The obtained information of synthesized samples have super paramagnetic nature. [ABSTRACT FROM AUTHOR]
