The high-pressure metallic phase of aluminunm antimnonide is super conducting [critical temperature Tc (P
125 kilobars) = 2.8°±0.2°K]. This transition temperature is significantly lower than the transition temperature of metallic germanium under an equivalent high pressure. A similar result had been previously found for superconducting indiumantimonide in comparison to tin.
