Nanocrystalline dilute magnetic semiconductor, Mn-doped ZnO, has been prepared by chemical route. The amorphous nature of the as-prepared sample was confirmed by X-ray diffraction analysis. Reitveld analysis of the annealed sample heated at 500°C for 30 min shows it is an anisotropic nanocrystalline phase. Transmission electron microscopy also confirms the anisotropic growth of Mn-doped ZnO. Saturation magnetization around 0.2 emu/gm has been achieved for the same sample, which is substantially higher than previously reported value. A decrease in magnetization with increasing annealing temperature is observed, which might be related to the effect of particle size.
