Abstract

We report the 63Cu NQR spectrum and nuclear relaxation rates for Cu(2) sites in 63Cu-enriched YBa2Cu3O6.64 (Tc ∼ 60 K). Nuclear spin-lattice relaxation rates exhibit a strong reduction of (T1T)-1 between 100 K and Tc. Cu(2) Knight shifts measured in a YBa2Cu3O6.7 sample of natural isotopic abundance are reduced substantially relative to YBa2Cu3O7.0 and show little change below Tc.
