It has been well understood that the Dzyaloshinskii-Moriya (DM) interaction is the origin of these textures, and the physics behind the DM interaction is the spin-orbital coupling (SOC). However the SOC shows its effect not only on the spins, but also on the electrons. In this paper, we will discuss effects of the SOC on the electron and spin transports in B20 compounds. An effective Hamiltonian is presented from symmetry analysis, and the spin-orbital coupling therein shows anomalous behaviors in anisotropic magnetoresistance (AMR) and helical resistance. New effects such as inverse spin-galvanic effect is proposed, and the origin of the DM interaction is discussed.", "revisions": [ { "version": "v1", "updated": "2014-12-22T21:33:53.000Z" } ], "analyses": { "subjects": [ "71.10.Ay", "72.10.Fk", "72.15.Gd", "75.10.Hk" ], "keywords": [ "metallic b20 helimagnets", "transport theory", "cubic helimagnets harboring nontrivial spin", "helimagnets harboring nontrivial spin textures", "b20 compounds" ], "publication": { "doi": "10.1103/PhysRevB.91.134401", "journal": "Physical Review B", "year": 2015, "month": "Apr", "volume": 91, "number": 13, "pages": 134401 }, "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015PhRvB..91m4401K" } } }
