摘要：

The H-1 nuclear spin-lattice relaxation rate, T1(-1), of the organic superconductor, kappa-(BEDT-TTF)2Cu-[N(CN)2]Br, has been measured. A remarkable peak has been observed in T1(-1) vs temperature in the superconducting state, similarly to the previous finding in the Cu(NCS)2 salt. This fact suggests that the anomalous enhancement of T1(-1) is a general characteristics of layered organic superconductors, very probably related to peculiarity of vortex dynamics.
