Abstract
Interlayer magnetoresistance measurements under the pressure of 6 kbar have been performed for the magnetic field induced organic superconductor $\lambda$ -(BETS) ₂FeCl ₄ 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. Key words. H-T phase diagram, BETS, pressure.
