Sažetak
Ac susceptibility measurements are reported for single crystals of the layered organic superconductor kappa -(BEDT-TTF)/sub 2/CuN(CN)/sub 2/Br. The value of the out-of-plane penetration depth lambda /sub b/(0) was found to be 133 mu m, consistent with earlier results. The temperature dependence of the in-plane superfluid density, with the value of in-plane component lambda /sub ac/(0) of the order of 1 mu m, is strongly linear in T, whereas the out-of-plane superfluid density varies as T/sup 2/ at low temperatures. The observed behavior is fully consistent with the one expected for d-wave superconductivity.
