Rh2Mo3N, with a noncentrosymmetric β-manganese structure, has been found to be superconducting with critical temperature Tc≈4.3K. Magnetic field dependence of resistivity, magnetization, and specific heat measurements show that its upper critical field of μ0Hc2∗∼7.41T comes close to, but does not exceed, the Pauli paramagnetic limit and that the 2Δ/kBTc value of about 3.62 is in accordance with a conventional s-wave superconductor. Andreev reflection spectroscopy measurements using both normal metal and half-metal show conclusively s-wave pairing with an isotropic gap.
