ZnO Doped with Fe and Mn Prepared by Sol-Gel Method

Article Preview

Abstract:

ZnO doped with iron (Fe) and manganese (Mn) were prepared by sol-gel method. The precursors for Fe-doped ZnO were zinc acetate and iron nitrate while those for Mn-doped ZnO were zinc nitrate and manganese nitrate. Crystal structures were characterized by means of XRD. The XRD patterns suggest the crystals are hexagonal wurtzite. Furthermore, the magnetic properties were studied by VSM. The hysteresis loops correspond to paramagnetism.
