Evidence for theT−12Singularity in Kondo Alloys

A $T^{-\frac{1}{2}}$ term is found in the resistivity-temperature relationship in the Ni-Pd-P-base amorphous alloys containing iron. This is interpreted as a result of the interference between scattering by magnetic impurities and that by nonmagnetic impurities. In this interpretation, an incoming conduction electron first interacts with the nonmagnetic impurities to form a spin-density fluctuation system which interacts with a magnetic impurity.
