Abstract
We found a clear evidence of anisotropic superconducting gap in the lo w-temperature specific heat of high-quality CeCo2 single crystals. The electronic specific-heat jump at T-C is reduced (Delta C-c/gamma T-C = 0.85) compared to the BCS value of 1.43 and C-e varies approximately as T-2 at low temperatures of T much less than T-C.
