Abstract

We determine the upper critical field ^μ0Hc2( ^Tc) of non-centrosymmetric superconductor Y₂C₃ using two distinct methods: the bulk magnetization M(T) and the tunnel-diode oscillator (TDO) based impedance measurements. It is found that the upper critical field reaches a value of 30 T at zero temperature which is above the weak-coupling Pauli paramagnetic limit. We argue that the observation of such a large ^μ0Hc2(0) in Y₂C₃ could be attributed to the admixture of spin-singlet and spin-triplet pairing states as a result of broken inversion symmetry.
