Research Abstract |
We have carried out 13C NMR experiment on a molecular superconductor ''-(BEDT-TTF)4[(H_3O)Ga(C_2O_4)3]・C_6H_5NO_2, which possesses the upper critical field more than twice larger than the Pauli depairing limit, and demonstrated that the superconducting pairs are in the spin-singlet state. This result indicates the possibility of unconventional superconducting state in high magnetic fields.
