摘要：
The temperature dependence of the nuclear transverse relaxation rate, 1/T2, of Cu-NQR in YBa2Cu3O7-y, and La2-xSrxCuO4 is measured in the superconducting and the normal states. The anomalous enhancement of 1/T2 at the Cu(1) and Cu(2) sites is observed at 35 K in YBa2Cu3O7-y but is not observed in the superconducting La2-xSrxCuO4. © 1990, THE PHYSICAL SOCIETY OF JAPAN.
