Abstract

We measured the low-temperature specific heat of the layered organic superconductor κ-(BEDT-TTF)2Cu(NCS)2 for the magnetic field directed along and across the conducting plane and found a difference between the two measurements. Our data indicate the existence of a nodeless superconducting state at zero field and low temperature. The field dependence of the specific heat anisotropy consists of two linear branches with the crossover field equal to the upper critical field perpendicular to the conducting plane.
