Sažetak
The anisotropic magnetic penetration depth lambda /sub b/(t) and lambda /sub ac/(t), where t=T/T/sub c/, in the layered organic superconductor kappa -(BEDT-TTF)/sub 2/CuN(CN)/sub 2/Br (abbreviated as kappa -ET-Br) are obtained from AC susceptibility data. We find lambda /sub b/(0)=133 mu m, consistent with earlier results and Delta lambda /sub b/(t)= lambda /sub b/(t)- lambda /sub b/(0) varies as t/sup 2/, which is new. Also, assuming lambda /sub ac/(0) approximately=1 mu m, we obtain Delta lambda /sub ac/(t) varies as t. The observed power laws are consistent with the ones expected in d-wave superconductivity.
