Detection of Topological Spin Textures via Nonlinear Magnetic Responses
Stepanova, Mariia; Masell, Jan; Lysne, Erik Nikolai; Schoenherr, Peggy; Köhler, Laura; Paulsen, Michael; Qaiumzadeh Javinani, Alireza; Kanazawa, Naoya; Rosch, Achim; Tokura, Yoshinori; Brataas, Arne; Garst, Markus; Meier, Dennis Gerhard (Peer reviewed; Journal article, 2021)Topologically nontrivial spin textures, such as skyrmions and dislocations, display emergent electrodynamics and can be moved by spin currents over macroscopic distances. These unique properties and their nanoscale size ... -
Dislocation-Driven Relaxation Processes at the Conical to Helical Phase Transition in FeGe
Schoenherr, Peggy; Stepanova, Mariia; Lysne, Erik Nikolai; Kanazawa, Naoya; Tokura, Yoshinori; Bergman, Anders; Meier, Dennis Gerhard (Journal article, 2021)The formation of topological spin textures at the nanoscale has a significant impact on the long-range order and dynamical response of magnetic materials. We study the relaxation mechanisms at the conical-to-helical phase ... -
Local dynamics of topological magnetic defects in the itinerant helimagnet FeGe
Dussaux, Antoine; Schoenherr, Peggy; Koumpouras, Konstantinos; Chico, Jonathan; Chang, Kevin; Lorenzelli, Luca; Kanazawa, Naoya; Tokura, Yoshinori; Garst, Markus; Bergman, Anders; Degen, Christian L.; Meier, Dennis (Journal article; Peer reviewed, 2016)Chiral magnetic interactions induce complex spin textures including helical and conical spin spirals, as well as particle-like objects such as magnetic skyrmions and merons. These spin textures are the basis for innovative ... -
Topological domain walls in helimagnets
Schoenherr, Peggy; Müller, Jan; Köhler, Laura; Rosch, Achim; Kanazawa, Naoya; Tokura, Yoshinori; Garst, Markus; Meier, Dennis (Journal article; Peer reviewed, 2018)Domain walls naturally arise whenever a symmetry is spontaneously broken. They interconnect regions with different realizations of the broken symmetry, promoting structure formation from cosmological length scales to the ...
