摘要：
The high-Tc superconductor YBa2(Cu0.99Fe0.01)3O7-δ was studied by Mössbauer spectroscopy and X-ray diffraction. Spectra taken at room temperature were fitted with four components. Annealing experiments showed that changes in the spectra at various temperatures are related to the nearest environment of Fe atoms rather than to the global lattice symmetry. Based on the results obtained, a model of lattice site assignment of Fe atoms has been proposed. © 1990 J.C. Baltzer A.G. Scientific Publishing Company.
