Abstract

The magnetic susceptibilities of La₂Mg_1-xZn_xIrO₆ (0< x <1), La₂NiIrO₆, La₂CuIrO₆, La₂LiIrO₆, BaLaMgIrO₆, BaLaFeIrO₆, BaLaCoIrO₆, BaLaNiIrO₆ and Sr₄IrO₆ have been measured as a function of temperature and applied magnetic field. Sr₄IrO₆, BaLaNiIrO₆ and BaLaCoIrO₆ order antiferromagnetically at 12, 87 and 56 K respectively. BaLaFeIrO₆ shows a spin-glass transition at 65 K. La₂NiIrO₆ and BaLaCoIrO₆ order as weak ferromagnets at 80 K and 70 K respectively. The solid solution La₂Mg_1-xZn_xIrO₆ shows a gradual change from antiferromagnetism (T_{N = 11.7 K}) when x = 0 to ferromagnetism (T_c = 9.5 K, µ_sat = 0.4 µ_B) when x = 1. The Ir(V) oxides La₂LiIrO₆ and BaLaMgIrO₆ are paramagnetic in the temperature range 6 K < T < 300 K. © 1993.
