Abstract
The organic conductor (MDT-TS)(AuI2)0.441 undergoes a metal-insulator transition at TMI=50 K, where MDT-TS is 5H-2-(1,3-diselenol-2-ylidene)-1,3,4,6-tetrathiapentalene. The static magnetic susceptibility demonstrates an antiferromagnetic ordering below this temperature. Hydrostatic pressure suppresses this insulating state, and a superconductivity appears at Tc=3.2 K above 10.5 kbar. The phase diagram demonstrates a transition from the incommensurate antiferromagnetic insulating state to a superconducting state in an organic conductor with a noninteger carrier number.
