Abstract
An NQR study of copper in YBa 2 Cu 3 O 7- y with the doping of Zn impurity has been performed. The nuclear spin lattice relaxation time, T 1 , of 63 Cu was measured. The 1/ T 1 of Cu in the CuO 2 plane follows the Korringa law in the normal state below 90 K, and is saturated above 100 K. From this result, it is expected that T 1 in the normal state of YBa 2 Cu 3 O 7- y follows the Korringa law below 90 K.
