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.

Mn, Fe doped ZnO powders (Zn0.95-xMnxFe0.05O2, x≤0.05) were synthesized by an ameliorated sol-gel method, using Zn(CH3COO)2, Mn(CH3COO)2and FeCl2as the raw materials, with the addition of vitamin C as a kind of chemical reducer. The resulting powder was subsequently compacted under pressure of 10 MPa at the temperature of 873K in vacuum. The crystal structure and magnetic properties of Zn0.95-xMnxFe0.05O2powder and bulk samples have been investigated by X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). X-ray photoelectron spectroscopy (XPS) was used to study chemical valence of manganese, iron and zinc in the samples. The x-ray diffraction (XRD) results showed that Zn0.95-xMnxFe0.05O (x≤0.05) samples were single phase with the ZnO-like wurtzite structure. No secondary phase was found in the XRD spectrum. X-ray photoelectron spectroscopy (XPS) showed that Fe and Mn existed in Zn0.95-xMnxFe0.05O2samples in Fe2+and Mn2+states. The results of VSM experiment proved the room temperature ferromagnetic properties (RTFP) of Mn, Fe co-doped ZnO samples.

Abstract In the present work, nanocrystalline Sb3+ ions doped Ni0.2Ba0.1Co0.7Fe2−xSbxO4 (0 ≦ x ≦ 0.1, step by 0.025) ferrites were prepared via sol-gel method. The spinel-phase structure of samples can be confirmed by X-ray diffraction (XRD) patterns. The composition and structure were further studied by fourier transform infrared spectroscopy (FTIR). There were two typical characteristic bands ν1 and ν2 related to the stretching vibrations in spinel ferrite in FTIR spectra. Energy dispersive spectrometer (EDS) analyzed the elements of samples. It indicated that the elements of Ni, Ba, Co, Fe, O and Sb existed in the samples. Vibrating sample magnetometer was used to characterize magnetic properties. The saturation magnetization decreased from 57.65 emu/g to 44.50 emu/g with the increasing Sb3+ ions content, which is attributed to Fe3+ ions replaced by the Sb3+ ions. Remanent magnetization and coercivity first decreased and then increased slightly.
