Abstract
We have obtained the parallel penetration depth of two representative compounds of layered organic superconductors, kappa-(BEDT-TTF)(2)Cu[N( CN)(2)]Br and alpha-(BEDT-TTF)(2)NH4(SCN)(4) by ac susceptibility meas urements. The former salt gives the depth of 190 mu m, while that for the latter is 1.4 mm. These values demonstrate that the NH4(SCN)(4) sa lt is more highly-two-dimensional than the Cu[N(CN)(2)]Br salt. The ac susceptibility under dc magnetic field probes peculiarities of the vo rtex dynamics.
