The effect of heat treatment on the m icrostructure and super-conducting properties of the eutectic alloy A1-11.3 at% Si prepared by the splat quenching technique has been studied. The negative magnetoresistivity in super conducting-normal transition was observed in the sample after annealing at 100℃ for 50 hours. Our results reveal the existence of two superconducting phases in this sample.
