When this resulting dipole moment interacts with gauge fields in the spin-texture region, an effective field is created that produces spin torques. These torques, like spin-orbit torques that occur when electrons are injected from a heavy metal into a ferromagnet, can display both damping-like and anti-damping-like properties. Finally, we demonstrate that such an interaction between the dipole moment and the gauge field introduces an anomalous velocity that can contribute to transverse electrical conductivity in the spin texture in a way comparable to the topological Hall effect.<\/jats:p>","DOI":"10.1088\/1361-648x\/acea10","type":"journal-article","created":{"date-parts":[[2023,7,24]],"date-time":"2023-07-24T18:32:57Z","timestamp":1690223577000},"page":"435802","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Spin torques and anomalous velocity in spin textures induced by fast electron injection from topological ferromagnets: The role of gauge fields"],"prefix":"10.1088","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6717-2881","authenticated-orcid":true,"given":"Satadeep","family":"Bhattacharjee","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9741-6955","authenticated-orcid":true,"given":"Seung-Cheol","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2023,8,2]]},"reference":[{"key":"cmacea10bib1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.109.096602","type":"journal-article","volume":"109","author":"Liu","year":"2012","journal-title":"Phys.
