• Effects of field annealing on MnN/CoFeB exchange bias systems 

      Quarterman, P; Hallsteinsen, Ingrid; Dunz, Mareike; Meinert, Markus; Arenholz, Elke; Borchers, Julie; Grutter, Alexander (Peer reviewed; Journal article, 2019)
      We report the effects of nitrogen diffusion on exchange bias in MnN/CoFeB heterostructures as a function of MnN thickness and field-annealing temperature. We find that competing effects occur in which high-temperature ...
    • Goldstone-like phonon modes in a (111)-strained perovskite 

      Marthinsen, Astrid; Griffin, Sinead M; Moreau, Magnus; Grande, Tor; Tybell, Per Thomas Martin; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2018)
      Goldstone modes are massless particles resulting from spontaneous symmetry breaking. Although such modes are found in elementary particle physics as well as in condensed-matter systems like superfluid helium, superconductors, ...
    • Temperature and Orientation Dependent Exchange Coupling in Epitaxial Oxide Micromagnets 

      Lee, Michael S.; Wynn, Thomas A.; Folven, Erik; Chopdekar, Rajesh V.; Scholl, Andreas; Retterer, Scott; Grepstad, Jostein; Takamura, Yayoi (Journal article; Peer reviewed, 2017)
      Soft x-ray photoemission electron microscopy with an in situ magnetic field has been used to study the relationship between ferromagnetic and antiferromagnetic spin alignment and the switching/reversal field of epitaxial ...
    • The role of antiferromagnetic spin axis on magnetic reconstructions at the (111)-oriented La0.7Sr0.3MnO3/ LaFeO3 interface 

      Hallsteinsen, Ingrid; Grutter, Alexander; Moreau, Magnus; Slöetjes, Samuel Dingeman; Kjærnes, Kristoffer; Arenholz, elke; Tybell, Per Thomas Martin (Journal article; Peer reviewed, 2018)
      Engineering of emergent properties at oxide interfaces is an exciting route towards realizing oxide electronics. Such properties are often the result of a balance between cooperating and competing mechanisms in the materials ...
