H-T phase diagram of λ-(BETS)2FeCl4 under pressure

Abstract

Interlayer magnetoresistance measurements under the pressure of 6 kbar have been performed for the magnetic field induced organic superconductor λ-(BETS)2FeCl4 to investigate the role of pressure and magnetic field. No evidence of the metal-insulator phase transition is observed down to 1.5 K and a broad superconducting transition occurs. A series of magnetic transition from antiferromagnetic to paramagnetic phase are observed with increasing magnetic field. © EDP Sciences.
