We report on a study of magnetic cluster in Co‐doped ZnO using neutron diffraction. The samples are fabricated by the sol–gel process and the structural properties are characterized by X‐ray diffraction and neutron diffraction. The diffraction data obtained by neutron are compared with the results of X‐ray diffraction and refined by the Rietveld refinement method. The secondary phases are detected by neutron diffraction in above 5 mol% Co‐doping of ZnO samples and the fractions of the phases in the samples are calculated. In particular, the Co metal phase is clearly observed in 30 mol% Co‐doped ZnO. However, these secondary phases are not detected by X‐ray diffraction due to reasons such as X‐ray absorption by Co K ‐edge and incoherent X‐ray scattering. We discuss the advantage of using neutron diffraction in studying the secondary phase and suggest the solubility limit of Co‐doping. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
