项目摘要
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.
通过扩展以前的理论,我们建立了分子动力学理论,它以第一原理的方式确定了金属和合金的磁结构。将该理论应用于Mn_3Pt合金,在25K下得到了与实验结果几乎一致的非共线磁结构。Mn_3Pt的电子结构计算表明,在费米面附近的X点附近形成了一个平带,d电子的能态密度有一个亚峰,其位置与费米能级的位置相一致。
