摘要：
The low-temperature specific heat of kappa-(BEDT-TTF)(2)X system, where X=Cu(NCS)(2) and Cu[N(CN)(2)]Br, was studied to clarify the structure of low-energy quasi-particle excitations over the superconductive gap. The power-law temperature dependence below about 1K and sensitive magnetic-field dependence imply that the electron-pairing in these superconductors is unconventional with line-nodes in the gap.
