Abstract

We demonstrate an extremely high upper-critical-field, B_c2, in the noncentrosymmetric heavy-fermion superconductor CeRhSi₃ for a magnetic field along the tetragonal c-axis. The robustness of the superconductivity over the magnetic field is outstanding among the known superconductors. The extremely large B_c2 is attributed to the absence of the paramagnetic pair-breaking effect characteristic of noncentrosymmetric superconductors.
