摘要：

3.5 GeV-Xenon ions-induced defects in Fe-doped 1.2.3 phases YBa2Cu3-xFexO7-δwith × = 1, 0.3 and 0.45 have been investigated by means of in situ resistance measurements at 100 K and Mossbauer spectroscopy at 300 K. Beside the exponential dependence of the resistance with Xe-fluence, the radiation effects result in the appearance on the Mossbauer absorption spectra of a fourth quadrupole doublet D4(δ≥0.3 mm/s, ΔQ41.1 mm/s) whose relative intensity increases with dose i.e. with latent track density. Concerning the distribution of Fe species on Cu sites in the unperturbed part of the sample, a strong interrelation between the variations of the relative areas of quadrupole doublets D, (ΔQ1~ 1.1 mm/s) and D3(ΔQ3~ 0.3 mm/s) under irradiation lead us to assign the corresponding Fe species substituted on Cu(1) sites ([CuCU], chains of corner sharing Cuo4groups), in agreement with heat treatment analysis. © 1990, Taylor & Francis Group, LLC.
