摘要：

Magnetization studies reveal that the ground state of kappa-(BEDT-TSF)(2)FeCl4 is J = 1/2 with weak antiferromagnetic correlations. Quantum oscillation studies indicate that the effective masses of the quasiparticles are considerably enhanced with respect to those of isostructural kappa-(BEDT-TSF)(2)GaCl4. We attribute the mass enhancement to spin fluctuation effects involving the Fe magnetic moments within the inorganic layer. [S0163-1829(98)00615-8].
