Abstract
The ac magnetic measurements on an organic metal, kappa- (BETS)(2)FeCl4 dow n to 60 mK revealed successive antiferromagnetic and superconducting phase transitions at about 0.65 K (approximate to T-N) and 0.1 K (approximate to T-C), respectively. These transitions correspond to the similar transitions in the Br-analogue, kappa-(BETS)(2)FeBr4 but the transition temperatures o f FeCl4 system are significantly lower than those of FeBr4 system (T-N = 2. 5 K; T-C = 1.1 K).
