摘要：

One of the four quadrupole doublets (A, B, C, and D) observed in Mössbauer spectra of orthorhombic (Y or RE)1Ba2(Cu1-xFex)307-δ(δ≈0) samples is identified with Fe dopant replacing a Cu site in twin planes. The site in question, labelled as D, is characterized by a quadrupole splitting ΔD in the range 1.6±0.1 mm/s. The D-site intensity is found to approach zero when the 1-2-3, material is driven tetragonal, either upon oxygen desorption, upon oxygen loading, or upon increasing the Fe-dopant concentration. © 1990 J.C.
