The first one uses the constrained moment method to build a spin spiral in real space, while the second method uses the generalized Bloch theorem approach to construct a spin spiral in reciprocal space. We show that although the two methods produce an overall similar total DMI energy, the dependence of DMI as a function of the spin spiral wavelength is dramatically different. We suggest that long-range magnetic interactions, that determine itinerant magnetism in transition metals, are responsible for this discrepancy. We conclude that the generalized Bloch theorem approach is more adapted to model DMI in transition metal systems, where magnetism is delocalized, while the constrained moment approach is mostly applicable to weak or insulating magnets, where magnetism is localized. dc.publisher arXiv dc.relation.url http://arxiv.org/abs/1710.10607v1 dc.relation.url http://arxiv.org/pdf/1710.10607v1 dc.rights Archived with thanks to arXiv dc.title Modeling Dzyaloshinskii-Moriya Interaction at Transition Metal Interfaces: Constrained Moment versus Generalized Bloch Theorem dc.type Preprint dc.contributor.department Material Science and Engineering Program dc.contributor.department Physical Science and Engineering (PSE) Division dc.contributor.department Spintronics Theory Group dc.eprint.version Pre-print dc.identifier.arxivid 1710.10607 kaust.person Dong, Yaojun kaust.person Belabbes, Abderrezak kaust.person Manchon, Aurelien dc.version v1 refterms.dateFOA 2018-06-13T17:56:02Z
