Abstract

Here, we report on systematic studies of the magnetic properties of Co and Cu codoped ZnO nanoparticles prepared by sol–gel technique. The effect of hydrogenation and shape on the magnetic properties of Zn0.93Co0.05Cu0.02O nanoparticles is presented. The Zn0.93Co0.05Cu0.02O nanoparticles and well-aligned Zn0.93Co0.05Cu0.02O nanorod array display ferromagnetic behavior at room temperature. Our results demonstrate the influence of shape and hydrogenation on the ferromagnetic properties of Zn0.93Co0.05Cu0.02O nanoparticles at room temperature.
