Abstract
Similar to the recently discovered organic conductor kappa-(BETS)(2)FeBr4 e xhibiting a transition from an antiferromagnetic metal phase to a supercond ucting phase at 1.0K, kappa-(BETS)(2)GaBr4 shows a super-conducting transit ion around 0.5-1.0K, indicating T-C of kappa-(BETS)(2)MBr4 (M = Fe, Ga) to be almost independent of the existence of magnetic anions; from these findi ngs a way to develop novel organic conductors with controlled antiferromagn etic interactions is suggested.
