MAGNETIC PHASE DIAGRAM IN FIELD INDUCED SUPERCONDUCTORS λ-(BETS)2FexGa1-xCl4

Electronic states have been investigated under high magnetic fields for quasi-two-dimensional organic conductors λ-(BETS)2FexGa1-xCl4 (x = 1.0, 0.47, 0.45, 0). Under magnetic field parallel to the c-axis, various electronic states appear, depending on x, field, and temperature. The global phase diagram for this alloy is presented and the evidence of the strong internal field due to the Fe moments is shown.
