英文摘要
We have formulated the molecular dynamics theory which determines the magnetic structures of metals and alloys in a first principle manner by extending the previous theory. Application of this theory to Mn_3Pt alloy at 25 K shows a noncollinear magnetic structure which is almost identical to that found in experiments. Electronic-structure calculations on Mn_3Pt reveals the formation of a flat band around the X point near the Fermi surface, and it is found that the nonmagnetic density of states of the d electron has a sub peak the location of which coincides with that of the Fermi energy.
