Abstract
We investigate by electrical transport the field-induced superconducting state (FISC) in the organic conductor . Below 4 K, antiferromagnetic-insulator, metallic, and eventually superconducting (FISC) ground states are observed with increasing in-plane magnetic field. The FISC state survives between 18 and 41 T and can be interpreted in terms of the Jaccarino-Peter effect, where the external magnetic field compensates the exchange field of aligned ions. We further argue that the moments are essential to stabilize the resulting singlet, two-dimensional superconducting state.
