Abstract

Nano-sized Fe doped ZnO (Zn1-xFexO where x=0.00, 0.005, 0.01, 0.02, 0.03, 0.04) powders were prepared by simple solution combustion method. The powder X-ray diffraction patterns of these samples showed that they are single phase without any secondary phases. The DC electrical conductivity measurements were carried out in the temperature range 300 K-650 K and it was found to increase with increase of temperature. At room temperature, DC electrical conductivity was evidenced to decrease with increase in Fe content. The hysteresis in the M-H behavior shows the presence of room temperature ferromagnetism in Fe doped ZnO..
