Further evidence for the [formula omitted] singularity in amorphous kondo alloys

Abstract

A T − 1 2 variation of resistivity with temperature near T = 0 is found in rapidly quenched amorphous NiPdP alloys containing up to 7 at.% Mn, providing further evidence for the existence of this new singularity. It is argued that the new resistivity term arises from interference between multiple scattering of conduction electrons by atoms in magnetic and non-magnetic states and is observed as a consequence of a short electron mean free path and breakdown of conservation of electron momenta in amorphous alloys.
