Abstract
The very sharp metal-insulator transition, which occurs at 8 K at ambient pressure in λ-(BETS) 2FeCl 4 is suppressed when applying magnetic fields >10T. This unusual phenomenon may be connected to ferromagnetic ordering of the Fe 3+ moments, which could drive some “evaporation” of the previously condensed conduction electrons, into a field-restored highly conducting state (FRHCS) in which oscillations of the magnetoresistance are reported.
