Here, utilizing scalar magnetic X-ray tomography under applied magnetic fields, we report the direct visualization of the three-dimensional (3D) shape of individual skyrmion strings in the room-temperature skyrmion-hosting non-centrosymmetric compound Mn<sub>1.4<\/sub>Pt<sub>0.9<\/sub>Pd<sub>0.1<\/sub>Sn. Through the tomographic reconstruction of the 3D distribution of the [001] magnetization component on the basis of transmission images taken at various angles, we identify a skyrmion string running through the entire thickness of the sample, as well as various defect structures, such as the interrupted and Y-shaped strings. The observed point defect may represent the Bloch point serving as an emergent magnetic monopole, as proposed theoretically. Our tomographic approach with a tunable magnetic field paves the way for direct visualization of the structural dynamics of individual skyrmion strings in 3D space, which will contribute to a better understanding of the creation, annihilation and transfer of these topological objects.<\/p>\n\n\n\n<p>See below for more information.<\/p>\n\n\n\n<ul><li>Aritcle URL :\u00a0<a href=\"https:\/\/www.nature.com\/articles\/s41563-021-01141-w\">https:\/\/www.nature.com\/articles\/s41563-021-01141-w<\/a><\/li><li>Nakatsuji-Sakai Lab. : <a href=\"https:\/\/www.nakatsuji-lab.phys.s.u-tokyo.ac.jp\/?lang=en\">https:\/\/www.nakatsuji-lab.phys.s.u-tokyo.ac.jp\/<\/a><\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"Magnetic skyrmions are topologically stable swirling spin textures that appear as particle-like objects in two [&hellip;]","protected":false},"author":7,"featured_media":3457,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[3],"tags":[11,36],"_links":{"self":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/3456"}],"collection":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/comments?post=3456"}],"version-history":[{"count":3,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/3456\/revisions"}],"predecessor-version":[{"id":3484,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/posts\/3456\/revisions\/3484"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media\/3457"}],"wp:attachment":[{"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/media?parent=3456"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/categories?post=3456"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.phys.s.u-tokyo.ac.jp\/en\/wp-json\/wp\/v2\/tags?post=3456"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
