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.eninfo:eu-repo/semantics/openAccessTetrathiafulvalen , Organischer Supraleiter , Josephson-Effekt530article
