摘要：

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