Popis: [19] Since the mixing ratio of the anions in the solution from which the crystals were grown was revealed to be almost identical to the stoichiometry determined by EPMA of the obtained crystal, the mixing ratio of the anions in the solution was adopted in the chemical formula of the crystal. The results of EPMA of k-(BETS)2FexGa1‐xBr1.0Cl3.0 are: for x = 0.50, Fe/Ga/Br/Cl = 0.51:0.49:1.13:2.85 (0.50:0.50:1.00:3.00); for x = 0.40, Fe/Ga/Br/Cl = 0.40:0.60:0.96:2.87 (0.40:0.60:1.00:3.00); for x = 0.30, Fe/Ga/Br/Cl = 0.32:0.68:1.11:3.07 (0.30:0.70:1.00:3.00); for x = 0.20, Fe/Ga/Br/Cl = 0.24:0.76:1.11:3.16 (0.20:0.80:1.00:3.00); for x = 0.10, Fe/Ga/Br/Cl = 0.12:0.88:1.04:3.22 (0.10:0.90:1.00:3.00). [20] Recent susceptibility measurements revealed that the angle between the easy axis of the antiferromagnetic structure and the c axis is about 35 in k-(BETS)2FeCl4 (E. Ojima, T. Sasaki, private communication). While the easy axis of k-(BETS)2FeBr0.6Cl3.4 is approximately parallel to the b* axis.
