摘要：

A pair of sharp Cu NQR signals and a broad Cu NQR signal were observed in high-Tc Pb cuprate. In the superconducting state, 1/T1 of Cu2 site decreases rapidly without enhancement just below Tc, which is similar to those for the CuO2 planes in Y-, La- and Bi-systems. The difference of the measured 1/T1 between both Cu sites in the normal state may be due to the difference of the density of states between them, supporting the recent band calculation result. © 1990, Elsevier Science Publishers B.V.
