Zn(1-x)Fe(x)O (x = 0.03,0.05,0.08,0.1) nanocrystals were synthesized from Zn nitrate and Fe nitrate reduced by citrate. The X-ray diffraction (XRD) shows that Zn(1-x)Fe(x)O (x <= 0.08) samples are single phase with the ZnO-like wurtzite structure, while the secondary phase ZnFe(2)O(4) is observed in Zn(0.9)Fe(0.1)O sample. Magnetic measurements indicate that Zn(1-x)Fe(x)O (x = 0.03, 0.05, 0.08) are ferromagnetic at room temperature and appear exchange bias varies with Fe concentration. The origin of the ferromagnetic is given by exchange and Zn vacancies in samples. Crown Copyright (C) 2008 Published by Elsevier B.V. All rights reserved.
