dc.description.abstract | We have prepared Zn-substituted YBa2Cu3-xZnxO7 (YBCO x = 0.0-0.09) and performed Cu-63,Cu-65 nuclear quadrupole resonance (NQR) measurements for the plane site at 300 and 100 K as a function of Zn concentration. The substitutional effects are observed in resonant frequencies and linewidths of spectra, and relaxation times as well as in the superconducting transition temperature. The spin-lattice relaxation rate 1/T-1 is reduced for the higher Zn concentration and the reduction is more significant at 100 K. The ratio of Cu-63,Cu-65 spin-lattice relaxation rates suggests that a magnetic contribution due to the antiferromagnetic spin fluctuation becomes weak as the Zn concentration increases. These effects confirm that the antiferromagnetic spin fluctuation of Cu 3d spins is suppressed by the Zn substitution due to the absence of local moment at the zinc site.
