Abstract
We measured the ac magnetic susceptibility for the layered organic superconductor EtMe3P[Pd(dmit)2]2 under pressure with a dc magnetic field applied perpendicular to the ac field. We investigated the dc field dependence of the ac susceptibility in detail and concluded that the superconductivity in EtMe3P[Pd(dmit)2]2 is an anisotropic three-dimensional superconductivity even at low temperatures, which contrasts with the large majority of other correlated electron layered superconductors such as high-Tc cuprate and κ-(ET)2X systems.
