Abstract
By measuring T1 of Cu NQR lines in Sm, Nd, Gd-Ba2Cu3O7-y the signals-which is observed at 20-23 MHz and 30-33 MHz in YBa2Cu3O7-y are assigned as arising from Cu1 and Cu2 site, respectively. 1/T1 follows the Korringa law in YBa2 (Cu0.98Zn0.02)3 O7-y below 90 K, although it is saturated above 100 K.
