"Evidence for Line Nodes in the Superconducting Energy Gap of Noncentrosymmetric CePt3Si from Magnetic Penetration Depth Measurements";
Physical Review Letters, 94 (2005), 2070021 - 2070024.

English abstract:
We report measurements of the magnetic penetration depth (T) in high-quality CePt3Si samples down to 0.049 K. We observe a linear temperature dependence below T0.16Tc, which is interpreted as evidence for line nodes in the energy gap of the low-temperature phase of this material. A kink in (T) at about 0.53 K may be associated with the second superconducting transition recently reported. The results are discussed in terms of the symmetry of the superconducting order parameter.
