| Superconductivity of indium diffused GaAs was investigated. The superconductivity in these samples was identified by the magnetic susceptibility and the characteristic field modulated microwave absorption. The static magnetic susceptibility was measured from 40 K down to 2.5 K. The result shows two distinctive diamagnetic contributions within 7 K-2.5 K range. These diamagnetic contributions were correlated with the excess of In and Ga metal in GaAs. |
