Lines of nodes in the superconducting gap of noncentrosymmetric CePt <inf>3</inf>Si

Abstract:

We report on magnetic penetration depth λ(T) measurements in CePt3Si down to 50 mK. It is found that λ(T) is proportional to T below T < 0.16Tc, which is interpreted as evidence for lines of nodes in the gap. A kink is observed in the penetration depth data around 0.5 K. We analyze the implications of these results on the symmetry of the superconducting pairing state. © 2006 American Institute of Physics.
