Cu(1) NQR spectra of the CuO chain site in Y1 _ xPrxBa2Cu3O7 (x = 0.1 and 0.2), and the 63Cu(1) NQR spin-lattice relaxation rates 1/T1 in Y0.9Pr0.1Ba2Cu3O7 have been measured. The half widths are about three times wider than those of the pure YBa2Cu3O7 . The peak frequencies are lowered by the Pr doping. This seems to indicate a decrease of on-site holes at the Cu(1) site. The relaxation rate 1/T1 is found to obey the same temperature dependence, 1/T1 = aT + bT3 as reported for pure YBa2Cu3O7.

Keywords: Y1 _ xPrxBa2Cu3O7; CuO chain site; NQR; spectrum; spin-lattice relaxation rate
