Abstract

The noncollinear magnetism and the enhancement of magnetocrystlline anisotropy (MCA) at the ∑(111) grain boundary (GB) in ferromagnetic Fe were analyzed. The first-principles full-potential linearized augmented plane-wave method, which included intra-atomic noncollinear magnetism, was used to analyze the enhancement of MCA and magnetic structures. It was observed that the GB enhanced the MCA by one order of magnitude from its bulk value and induced a pinning effect on the magnetization rotation or magnetic domain wall motion. It was also observed that by breaking the spatial translational symmetry in a crystalline solid, the GB exhibited a magnetic noncollineraity.
