摘要：

The low-temperature specific heat of single crystals of kappa-(BEDT-TTF)(2)Cu[N(CN)(2)]Br was studied in the temperature range between 0.11 and 4.5 K. The electronic specific heat, C-el, in the superconducting state shows a quadratic temperature dependence that is most reasonably attributed to the quasiparticle excitations found in unconventional superconductors with line nodes in the gap structure. The magnetic-field dependence of the temperature-linear term in C-el is also consistent with this picture of superconductivity.
