Abstract

We studied the main and the satellite signals of plane-site Cu(2) nuclear quadrupole resonance (NQR) spectra in optimally doped YBa2(Cu 1-xZnx)3O7-δ. The Cu nuclear spin-lattice relaxation time is found to distribute in the broadened Cu(2) NQR spectra. This is in contrast to nearly frequency independent relaxation in slightly oxygen-deficient YBa2Cu3Oy. The Cu nuclear spin-lattice relaxation time of the Zn-induced satellite signal is shorter than that of the main signal, suggesting a locally enhanced magnetic correlation by Zn. From the analysis of Zn-induced Cu NQR relaxation, the origin of pair-breaking mechanism due to Zn impurity is discussed.
