• 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 ...
    • Effect of (111)-oriented strain on the structure and magnetic properties of La2/3Sr1/3MnO3 thin films 

      Bolstad, Torstein; Lysne, Erik Nikolai; Hallsteinsen, Ingrid; Arenholz, E; Østerberg, Ulf Lennart; Tybell, Per Thomas Martin (Journal article; Peer reviewed, 2018)
      Using strain, i.e. subtle changes in lattice constant in a thin film induced by the underlying substrate, opens up intriguing new ways to control material properties. We present a study of the effects of strain on structural ...
    • Magnetic and geometric control of spin textures in the itinerant kagome magnet Fe3 Sn2 

      Altthaler, Markus; Lysne, Erik Nikolai; Roede, Erik Dobloug; Prodan, Lilian; Tsurkan, Vladimir; Kassem, Mohamed A.; Nakamura, Hiroyuki; Krohns, Stephan; Kézsmárki, István; Meier, Dennis Gerhard (Peer reviewed; Journal article, 2021)
      Magnetic materials with competing magnetocrystalline anisotropy and dipolar energies can develop a wide range of domain patterns, including classical stripe domains, domain branching, and topologically trivial and nontrivial ...
    • Thickness dependent uniaxial magnetic anisotropy due to step-edges in (1 1 1)-oriented La0.7Sr0.3MnO3 thin films 

      Bolstad, Torstein; Lysne, Erik Nikolai; Österberg, Ulf Lennart; Tybell, Per Thomas Martin (Journal article; Peer reviewed, 2019)
      The magnetic anisotropy of films of La0.7Sr0.3MnO3 grown on vicinal (1 1 1)-oriented SrTiO3 substrates are investigated. For temperatures above the tetragonal – cubic structural phase transition temperature of the substrate, ...
    • Ultrafast Optical and Magneto-Optical Kerr Effect Spectroscopy on Condensed Matter 

      Lysne, Erik Nikolai (Master thesis, 2017)
      In this masters project, an ultrafast optical spectroscopy system has been constructed and tested. The system was built as an extension to an existing spectroscopy system, centered around a mode-locked Ti:Sapphire femtosecond ...
