Abstract

The authors report C13 NMR line position, line shape, and spin-spin relaxation rate data for the quasi-two-dimensional organic superconductor κ-(ET)2Cu[N(CN)2]Br (Tc=11.6 K), for an aligned single crystal. The data make possible identification of the crystallographic site responsible for the NMR lines, clarify a line broadening transition near 150 K, and probe the nature of the fluxoid lattice below Tc. © 1996 The American Physical Society.
