High purity Fe2O3 doped ZnO composites were grown by standard solid state reaction method in air at temperature range of 1350 °C for 10 h. The structures of the grown samples were investigated by X-ray diffraction studies. Single phase ZnO was observed indicating substitutional addition Fe2+ ion in Zn lattice. Electron density studies were carried out and sharing of the electrons between the atoms were observed in different planes and directions. Room temperature ferromagnetism can be observed in Fe-doped ZnO using vibrating sample magnetometry showing an increasing trend as the dopant concentration increases. Scanning electron microscopy micrographs along with energy dispersive X-ray analysis were taken to study of structure of the grown composites and to find the presence of Fe in ZnO.
