摘要：

The first study of thermal conductivity, kappa, in a quasi-two-dimensional organic superconductor of the kappa-(BEDT-TTF)(2)X family reveals features analogous to those already observed in the cuprates. The onset of superconductivity is associated with a sudden increase in kappa which can be suppressed by the application of a moderate magnetic field. At low temperatures, a finite linear term-due to a residual electronic contribution-was resolved. The magnitude of this term is close to what is predicted by the theory of transport in unconventional superconductors. [S0031-9007(98)07704-7].
