The Nanoparticles ( . with x = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1, With exposure to a calcination temperature of 100, 300, 600 and 900 °C ) synthesized by the Co-precipitation method .The structural and magnetic properties of the products were determined and characterized in detail by X-ray diffraction (XRD), High Resolution -Transmission Electron Microscope (HR-TEM), Energy Dispersive X-ray Spectroscopy (EDX) , Fourier Transform Infrared (FTIR) and vibrating sample magnetometer (VSM). These results provided that all the samples prepared at the nano-scale. X-ray analysis showed that the samples were cubic spinel structural ( kind of inverse spinel oxide).The crystallinity is improved with the increases calcination temperature for all samples and that proved by the FT-IR , XRD and EDX results and compound purity fabricated. HR-TEM analysis showed that nanoparticles size and the shape based on the Zn concentration & the calcination temperatures and also indicates that degree of agglomeration for all samples. VSM analysis showed that The C4 ( at 600°C) is best sample in Magnetic &structure properties where it’s super-paramagnetic behavior.
