| 摘 要： | 本文研究了热处理对急冷(快速淬火)Al-11.3at％Si共晶合金的微观结构和超导电性的影响。实验发现100℃/50hr退火样品在超导-正常转变区内有负磁阻效应,这表明在这种样品中存在两个超导相。

| Abstract: | 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. |
