| Abstract: | Three binary A-15 compounds (Zr4Sn, Ta3Sb, Ta4Au) were reinvestigated and all three found to be superconducting below 1 ?K. Ternary compounds V3(Al, X), (X=As, Ge, Au) were also investigated in the composition range where the A-15 structure is stable. The extrapolated superconducting transition temperature of the compound V3Al, if it existed in the A-15 form, is ～ 17 ?K. |
