Abstract

Spin-spin and spin-lattice relaxation rates of Cu(2) were measured on YBa2Cu3O7 in the normal and superconducting states. The spin-spin relaxation data are interpreted within the framework of the antiferromagnetic Fermi liquid theory of Millis, Monien and Pines, and the temperature dependence of the antiferromagnetic correlation length in the normal state is found to be consistent with that obtained from the spin-lattice relaxation data. In the superconducting state the spin-spin relaxation time becomes significantly longer. This indicates that the real part of the spin susceptibility at large momenta is reduced in the superconducting state.
