场论在磁性材料中的应用

On application of field theory to magnetic materials

将挠率场应用于非共线系统得到了适用于非共线磁系统的挠率-自旋-密度泛函理论(TSDFT)。用挠率场来表示磁性的非共线性后得到的非共线磁系统的有效单粒子方程可以精确求解,该方法明显优于缀加球面波法、局域自旋-密度近似方法和修正缀加球面波法。

The torsion and spin-density-functional theory (SDFT) was given by adding torsion fields to the non-collinear magnetic system. The torsion represents the non-collinear part of the non-collinear magnetic system. The accurate single particle equation was achieved. The TSDFT is more advanced than the ASW, full-potential and MASW methods.
