Abstract

We report noncollinear magnetism phenomena by means of several recent examples: (a) enhancement of magnetocrystalline anisotropy in ferromagnetic (FM) Fe films by intra-atomic noncollinear magnetism, (b) noncollinear magnetic structures of domain walls in FM Fe and antiferromagnetic NiMn, and (c) curling spin and orbital structures in the vortex core of an Fe quantum dot, as obtained from the first principles full-potential linearized augmented plane method including noncollinear magnetism with no shape approximation for the magnetization. These results are in good agreement with experiments, and give new information about magnetic phenomena at surfaces and in nanostructures.
