摘要：

Both specific heat and resistance measurements of organic superconductor kappa-(ET)(2)Cu(NCS)(2) under magnetic field were performed. Upper critical fields, obtained from the specific heat data, are significantly less than those from the magnetoresistance measurements. At temperatures below 2 K and magnetic fields below 1 T, we observed additional power dissipation due to the field sweep. This effect may be attributed to the existence of irreversibility line.
