Saturation of low temperature electrical resistance in the amorphous (Fe1−xNix)75P16B6Al3 alloy system

Abstract
We have measured the electrical resistance of amorphous ferromagnetic Fe75P16B6Al3 and Fe60Ni15P16B6Al3 down to 20 mK. It is found that the resistance saturates and reaches a constant value below about 80 mK in contrast to earlier low temperature studies on amorphous ferromagnets. The present results are in reasonable agreement with recent theories.
