Abstract
Both specific heat and resistance measurements of organic superconductor ka ppa-(ET)(2)Cu(NCS)(2) under magnetic field were performed. Upper critical f ields, obtained from the specific heat data, are significantly less than th ose 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 irrevers ibility line.
