Abstract
We predict that a topological disorder is the main driving force for t he formation of a big magnetic moment on Mn in Al86Mn14, Al80Mn20, and Al60Mn40 liquids, which it would be interesting to check experimental ly. This conclusion is further supported by comparing the results for liquid Al86Mn14 with its crystalline counterpart Al6Mn which is parama gnetic due to the van Hove singularity in the density of states. We co mpare the Anderson and Stoner scenarios for the moment onset in relati on to the present results.
