A metallic phase of gallium antimonide, obtained by quenching at approximately 120 kilobars to 77 degrees K and then releasing pressure, is a superconductor. The transition temperature depends on the annealing conditions; for samples annealed at 250 degrees C under pressure before quenching, it is 4.24 degrees +/- 0.10 degrees K, and H(c2) (the critical field) equals 2640 gauss at 3.50 degrees K. This temperature is higher than the 2.1 degrees K reported for metallic indium antimonide.
