The Magnetic Properties of Zn0.98Fe0.02O with Additional Cu Doping
Samples Zn0.98Fe0.02O doped with additional Cu have been fabricated by a coprecipitation method. It is found that Zn0.98Fe0.02O 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 model relative to holes.
