摘要: Nuclear quadrupole resonance (NQR) signals of Cu have been discovered in the high- T c superconducting oxide Bi–Pb–Sr–Ca–Cu–O with =109 K. It has observed that there are two sites a different coupling. The temperature dependence nuclear relaxation rate, 1/ 1 , was similar to CuO 2 plane YBa 3 O 7 . is found for site demonstrates reflection strong Cu-d spin correlation.
