| 中文摘要 | Comprehensive studies of X-ray diffraction, oxygen content, superconductivity and Mossbauer effect have been made on FexCu1-xBa2YCu2O7+y superconductors (0.00 <= x <= 0.70) synthesized by ambient (AM) and high pressure (HP). Results indicate that all the HP-samples have tetragonal structure, smaller lattice parameter c and unit-cell volume than the AM-samples. The studies of oxygen content, and Mossbauer spectroscopy indicate that the HP-samples have higher oxygen content, carrier concentration and average valence of Fe than the AM-samples. Moreover, for the HP-samples more Fe atoms located in Cux(x) chains have fivefold-oxygen coordination. These are important reasons for the enhancement of T-c in the HP-samples. (c) 2005 Elsevier Ltd.
