Institute of Physics and Electronic Engineering, Zhengzhou University of Light Industry, Zhengzhou, China . ABSTRACT Samples Zn 0.98 Fe 0.02 O doped with additional Cu have been fabricated by a coprecipitation method. It is found that Zn 0.98 Fe 0.02 O without additional doping shows weak ferromagnetism at room temperature. The Cu doping has induced a light increase of magnetization in low temperature of 10 K. This result is consistent with bound magnetic polaron mode...
