Huang, J. Wang, X. Zhong, G. Zhou, H. Yan] In this paper, Ni-doped ZnO (Zn1−x Ni x O, in which 0≤x≤0.05) diluted magnetic semiconductors nanoparticles are prepared by an ultrasonic assisted sol-gel process. Transmission electron microscopy shows sphere-like nanoparticles with an average size of about 25nm. From the analysis of X-ray diffraction, the Ni-doped ZnO nanoparticles are identified to be a wurtzite structure, but impurity phases are observed when the Ni content x reaches 0.05. Sample structures are further studied by Raman spectra, from which a broad and strong Raman band in the range of 500-600cm−1 is observed in Zn1−x Ni x O. With the increment of x, wurtzite structures degrade gradually. The magnetic properties are measured using superconducting quantum interference device at room temperature; the Zn1−x Ni x O (x≤0.02) nanoparticles show ferromagnetism. However, for the sample of Zn0.95Ni0.05O, paramagnetism is observed, which may be ascribed to ferromagnetic-antiferromagnetic competition. Springer Science+Business Media, LLC, 2007 Huang G.
