| Abstract: | The effects of a magnetic field on the Mott transition, a longstanding issue in condensed matter physics, are studied using magnetoresistance measurements for organic Mott insulators, lambda-(BETS)2GaBrxCl4-x, up to 55 T. We demonstrate that an insulator-to-metal transition with a first-order nature and a successive superconductor-toinsulator-to-metal transition are induced by magnetic fields. We discuss the difference in magnetic susceptibility between the insulating and metallic phases, which is a key factor in inducing these transitions. Field induced transitions in experimentally feasible fields under ambient pressure conditions lead to further experimental verification of Mott transitions. |
