• Coexisting spin-flop coupling and exchange bias in LaFeO3/La0.7Sr0.3MnO3 heterostructures 

      Olsen, Fredrik Kjemperud; Hallsteinsen, Ingrid; Arenholtz, Elke; Tybell, Per Thomas Martin; Folven, Erik (Journal article; Peer reviewed, 2019)
      Exchange bias occurs in field-cooled antiferromagnet/ferromagnet systems and can most often be explained in terms of uncompensated magnetic moments at the interface that are pinned in their orientation during field cooling. ...
    • Effects of array shape and disk ellipticity in dipolar-coupled magnetic metamaterials 

      Slöetjes, Samuel Dingeman; Digernes, Einar; Strømberg, Anders; Olsen, Fredrik Kjemperud; Bang, Ambjørn Dahle; N'diaye, Alpha T; Chopdekar, Rajesh V.; Folven, Erik; Grepstad, Jostein (Peer reviewed; Journal article, 2021)
      Two-dimensional lattices of dipolar-coupled thin film ferromagnetic nanodisks give rise to emergent superferromagnetic (SFM) order when the spacing between dots becomes sufficiently small. In this paper, we define micron-sized ...
    • Effects of lattice geometry on the dynamic properties of dipolar-coupled magnetic nanodisk arrays 

      Slöetjes, Samuel Dingeman; Digernes, Einar; Klewe, Christoph; Shafer, Padraic; Li, Qian; Yang, M.; Qiu, Z.Q.; N'diaye, Alpha T; Arenholz, Elke; Folven, Erik; Grepstad, Jostein (Journal article; Peer reviewed, 2019)
      We have studied the impact of lattice geometry on the dynamic properties of close-spaced arrays of circular nanomagnets, also known as magnonic crystals. To this end, we prepared 2D nanomagnet arrays with both square and ...
    • Exchange explosions of topological edge defects in a square micromagnet 

      Slöetjes, Samuel Dingeman; Folven, Erik; Grepstad, Jostein (Peer reviewed; Journal article, 2020)
      ) with a flux-closure magnetic ground state were investigated by micromagnetic simulations. The system was excited with an applied magnetic field, displacing the vortex core sufficiently far from its equilibrium position ...
    • Uniaxial Néel vector control in perovskite oxide thin films by anisotropic strain engineering 

      Kjærnes, Kristoffer; Hallsteinsen, Ingrid; Chopdekar, R. V.; Moreau, Magnus; Bolstad, Torstein; Svenum, Ingeborg-Helene; Selbach, Sverre Magnus; Tybell, Per Thomas Martin (Peer reviewed; Journal article, 2021)
      Antiferromagnetic (AF) thin films typically exhibit a multidomain state, and control of the AF Néel vector is challenging, as AF materials are robust to magnetic perturbations. In this paper, uniaxial Néel vector control ...
