Abstract

The zero-bias anomaly in point-contact characteristics of the organic superconductor α_t-(BEDT-TTF)₂I₃ is investigated as a function of temperature and magnetic field. It is found that the zero-bias anomaly is insensitive to magnetic fields up to 5 T. In contrast, a structure at 5 meV, conventionally designated as the superconducting gap–but which is 4 times larger than the expected BCS gap–is strongly affected by magnetic fields above 1 T.
