- We report on the synthesis of Fe-doped ZnO with nominal composition of Zn0.99Fe0.01O by using a
coprecipitation method. X-ray diffraction and selective area electron diffraction studies reveal a
single phase wurtzite crystal structure without any secondary phase. Field emission transmission
electron microscopy measurements infer that Zn0.99Fe0.01O have nanorod-type microstructures.
Magnetic hysteresis measurement performed at different temperatures show that Zn0.99Fe0.01O
exhibits a weak ferromagnetic behavior at room temperature. A detailed investigation of the
electronic and local structure using O K-, Fe L3,2 near edge x-ray absorption fine structure suggests
that Fe is substituting Zn in ZnO matrix and is in Fe3+ state.
