Abstract
Experiments of amorphous films of chromium and manganese show that the samples exhibit resistivity minima of the Kondo type. An argument is proposed whereby, due to structural disorder, a small fraction of magnetic sites within the otherwise magnetically ordered system, could be magnetically free. This would then allow a resistivity minimum similar to that observed for dilute magnetic impurities in a non-magnetic matrix.
