摘要：
We report on (63)Cu-NQR frequency nu(NQR) measurements on various high-T(c) superconductors. An empifical relationship between T(c) and nu(NQR) is presented. We attribute this finding to variations in the valence state of the in-plane Cu ions which, due to the unusual electric polarizability of the O(2-) ions, depends sensitively on the Cu-O distance.
