摘要：

Superconductivity has been found in the rare earth iridium borides with the general formula MIr4B4 and in the pseudoternary (YxLu1-x)-Ir4B4 system, M being a rare earth element. The pure phase in itself is only metastable at best. The compounds were found to crystallize with the primitive tetragonal CeCo4B4-type structure. The close correlation between superconductivity, magnetism and structural metastability is demonstrated with the study of the pseudoternary systems M(IrxRh1-x)4B4 (x = 0.1 and 0.5) and Er(IrxRh1-x)4B4. © 1979.
