High-Temperature Spin-Fluctuation Resistivity inAlMn

Abstract
The resistivity of AlMn alloys of concentrations up to 5% is found to decrease linearly in temperature above 50 K, while at lower temperatures it follows the same T2 behavior observed at lower concentrations. The linear behavior of ρ(T) rules out the possibility that AlMn is a Kondo system with TK500 K. Possible explanations in terms of localized spin fluctuations are suggested.
