在为大型螺旋装置的螺旋线圈研制的池沸腾型超导体中，观察到由于铝稳定剂电阻率的意外增强而导致恢复电流的退化。测得的电阻率与磁场的关系表明，这是一种异常磁电阻率。金属-金属复合材料中的霍尔效应被认为是解释这一现象的最合理的候选者。我们将我们的数据与基于该模型的计算值进行了比较，证实该模型可以很好地解释实验结果。
Degradation of recovery current due to the unexpected enhancement of resistivity of aluminum stabilizers has been observed in pool-boiling-type superconductors that have been developed for the helical coils of Large Helical Device. Dependence of the measured resistivity on the magnetic field suggests that this is a kind of anomalous magnetoresistivity. The Hall effect in metal-metal composites is considered to be the most plausible candidate to explain this observation. We compared our data with the calculated values based on this model and confirmed that this model explains the experimental results well.
