Magnetization studies reveal that the ground state of {kappa}-(BEDT-TSF){sub 2}FeCl{sub 4} 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){sub 2}GaCl{sub 4}. We attribute the mass enhancement to spin fluctuation effects involving the Fe magnetic moments within the inorganic layer. {copyright} {ital 1998} {ital The American Physical Society}
