Abstract
The Co doped ZnO (Zn1-xCoxO; x = 0.00, 0.02, 0.06 and 0.10) nanoparticles were synthesized using the co-precipitation method. Characterization techniques help to determine the different structural and magnetic properties. XRD pattern help to identify the structure of sample and confirms the phase confirmation. FTIR (Fourier transform infrared) characterization help to determine the functional groups present in the sample. It is based on the absorption phenomenon of sample. VSM characterization helps to understand the magnetic properties of samples. The spontaneous magnetization was found to be 0.1 emu/gm for pure ZnO which increases to 0.2 emu/gm with the 10% doping of Co in ZnO.
