摘要：

Samples of composition Zn0.9Co0.1O, Zn0.9Ni0.1O, Zn0.9Co0.06Ni0.04O were prepared by powder metallurgy method. Structural property was studied by X-ray diffractometer (XRD), and Fourier transform infrared spectroscopy (FTIR). Magnetic, electrical and optical properties were studied by vibrating sample magnetometer (VSM), four point probe method and UV-Visible spectrophotometer, respectively. Single phase wurtize structure was obtained for Zn0.9Co0.1O and Zn0.9Co0.06Ni0.04O, while a secondary phase of NiO was found in Zn0.9Ni0.1O. The bandgap energy found in all samples was less than pure ZnO. Scanning electron microscope (SEM) studied surface Morphology. Moreover, room temperature ferromagnetism (RTFM) was observed for all samples. (C) 2015 Published by Elsevier Ltd.
