    • 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 ...

    • Ultrafast generation and dynamics of isolated skyrmions in antiferromagnetic insulators 

      Khoshlahni, Rohollah; Qaiumzadeh, Alireza; Bergman, Anders; Brataas, Arne (Peer reviewed; Journal article, 2019)
      Based on atomistic spin dynamics simulations, we report the ultrafast generation of single antiferromagnetic (AFM) skyrmions in a confined geometry. This process is achieved through an effective magnetic field induced by ...
