Summary

The aluminium stabilizer, which is used in composite superconductors, in external fields at 4.2 K provides a remarkable enhancement of magnetoresistance as compared to predictions by conventional theory. In order to study the cause of this anomalous behaviour, the authors measured the electric resistivities of copper-clad aluminium conductors having rectangular cross-sections in various magnetic fields at 4.2 K. The predicted resistivities were consistent with the authors' experimental results, leading them to conclude that the current caused by the Hall effect is the main origin of the anomalous magnetoresistance and its anisotropy. They discussed a method to reduce the anomalous resistivity.
