摘要：

Cu-63,Cu- 65 NMR spectra and relaxation measurements in RuSr2GdCu2O8; in the temperature range 5-300 K; are reported. From the second-order quadrupole broadening of the NMR line the quadrupole coupling constant turns out nu(Q) similar or equal to 28.5 MHz: NMR line broadening, possibly related to Ru spins ordering, is observed on cooling. The spin-lattice relaxation rates 2W; involving the in-plane magnetic correlation length, do not show critical behavior above the ordering temperature. On approaching the superconducting transition 2W displays a temperature dependence similar to the one in underdoped YBCO. (C) 2003 Elsevier B.V. All rights reserved.
