Abstract

We report the ⁶³Cu NQR spectrum and nuclear relaxation rates for Cu(2) sites in ⁶³Cu-enriched YBa₂Cu₃O_6.64 (T_c ∼ 60 K). Nuclear spin-lattice relaxation rates exhibit a strong reduction of (T₁T)^-1 between 100 K and T_c. Cu(2) Knight shifts measured in a YBa₂Cu₃O_6.7 sample of natural isotopic abundance are reduced substantially relative to YBa₂Cu₃O_7.0 and show little change below T_c.
