In contrast to the other magnetic Rare Earth (RE) ions for which the cubic Laves REIr2 compound is ferromagnetic, YbIr2 and TmIr2 are antiferromagnetic below 0.40 and 0.05 K, respectively. Both are trivalent above 4 K, with a possible reduced moment for TmIr2 below 0.3 K. In addition, CeIr2 and LuIr2 are superconductive below 0.20 and 0.23 K, respectively. © 1985.
