In order to better understand the field-resistant superconducting phase, an international team of researchers (Germany, Japan, France) conducted magnetic-torque and magnetotransport measurements in pulsed magnetic fields. They determined the record-breaking upper critical field of ?0Hc2???73?T and its evolution with angle. The normal-state Hall effect experiences a drastic suppression indicative of a reduced band polarization above Hm in the angular range around 30° caused by a partial compensation between the applied field and an exchange field. According to the researchers this promotes the Jaccarino-Peter effect as a likely mechanism for the reentrant superconductivity above Hm… read more. Open Access TECHNICAL ARTICLEÂ
