A room temperature ferromagnetic Fe doped ZnO bulk sample has been synthesized by co-doping 2 at(percent) Mn with 2 at(percent) Fe in ZnO. The final firing temperature for the preparation of the Zn_(0.96)Mn_(0.02)Fe_(0.02)O sample is the same as the final firing temperature for the preparation of the Zn_(0.98)Mn_(0.02)O sample and in this case it is found to be 490 deg C. It has been found that room temperature ferromagnetism in Zn_(0.96)Mn_(0.02)Fe_(0.02)O is a factor of 1.6 times more than that observed in Zn_(0.98)Mn_(0.02)O samples. The size of the saturation magnetic field for the Zn_(0.96)Mn_(0.02)Fe_(0.02)O sample is, however, only a factor of 7 times more than that observed for nanocrystalline undoped ZnO.
