摘要：

In this letter, the authors report a number of indirect pieces of evidence which suggest that at a low temperature, which is still above the superconducting transition temperature T//s//c, the material undergoes a diffuse phase change to a relaxor-type ferroelectric state. Such a transition has already been suggested by J. F. Scott based upon temperature dependence of the Raman scattering. In particular the appearance of a peak at 646 cm** minus **1 at temperatures below 240 K in the yttrium compound (Re equals Y) has been taken as indicating a transition from a non-polar mmm crystal symmetry to a polar mm2 symmetry. A hypothetical discussion of a possible relation between high-temperature superconductivity and 'quasi-ferroelectricity' has also been given by Zhongjin Yang and co-workers.
