A. Sato et al., TEMPERATURE-COMPOSITION PHASE-DIAGRAM OF THE ORGANIC ALLOYS, LAMBDA-BETS2(FEXGA1-X)CL-4, WITH MIXED MAGNETIC AND NONMAGNETIC ANIONS, Chemistry Letters, (7), 1998, pp. 673-674
The electrical properties of a series of lambda-type BETS conductors,
lambda-BETS2(FexGa1-x)Cl-4 can be controlled continuously by varying t
he x-value. The system shows a metal-insulator transition for x>x(1) (
x(1)approximate to 0.5) and a superconducting transition for x<x(1). T
he T-x phase diagram indicates that the system shows the superconducto
r-insulator transition for x(2)<x<x(1) (x(2)approximate to 0.35).
