Vf. Gantmakher et al., SUPERCONDUCTING RESPONSE IN BULK CDSB ALLOY NEAR THE LOCALIZATION THRESHOLD, Physica. B, Condensed matter, 194, 1994, pp. 1083-1084
Experiments with metastable CdSb alloy demonstrate superconducting (S)
response on the insulating side of the metal (M)- insulator(I) transi
tion. This response dissappears with lowering the temperature.
