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.
