Pure and Mn (2.5 %, 5 % and 10 %) doped CuO nanoparticles were synthesized via chemical process of ultrasonic spray pyrolysis method. The crystal structure and grain size of the particles were determined using XRD. The optical properties of the samples were investigated using UV-Visible spectroscopy. The SEM micrographs revealed the surface morphology of sphere-shaped particles in all samples. The ZFC magnetization exhibits a sharp peak at 32 K and the FC magnetization saturated below this peak temperature. This is a characteristic feature of typical spin-glass behavior. In addition, the AC conductivity curves show an increasing conductivity value with increasing Mn content. The enhanced conductivity is due to the Mn doping in CuO induce defects in grain boundary.
