The electrical and magnetic properties of a series of magnetic organic conductors, ϰ‐(BETS) 2 FeBr x Cl 4– x [BETS = bis(ethylenedithio)tetraselenafulvalene], are presented. By collecting the experimental results of the electrical resistivities and magnetic susceptibilities, the temperature vs. x ‐value phase diagram of ϰ‐(BETS) 2 FeBr x Cl 4‐ x (0 ≤ x ≤ 4) has been obtained. It is shown that the magnetic interaction tends to decrease with increasing Cl content, suggesting the importance of the intermolecular magnetic interaction through the Br atom.
