 Abstract: We study the superconducting properties of the non-centrosymmetric compound LaNiC2 by measuring the London penetration depth Delta lambda(T), the specific heat C(T, B) and the electrical resistivity rho(T, B). Both Delta lambda(T) and the electronic specific heat C-e(T) exhibit behavior at low temperatures that can be described in terms of a phenomenological two-gap Bardeen-Cooper-Schrieffer (BCS) model. The residual Sommerfeld coefficient in the superconducting state, gamma(0)(B), shows a rapid increase at low fields and then an eventual saturation with increasing magnetic field. A pronounced upturn curvature is observed in the upper critical field B-c2(T) near T-c. All these experimental observations support the existence of two-gap superconductivity in LaNiC2.
