• Fabrication of Multiferroic Tunnel Junctions on (111)-oriented SrTiO3 

      Kjærnes, Kristoffer (Master thesis, 2016)
      The phenomenon of quantum mechanical electron tunneling is widely used in device technology, of which magnetic tunnel junctions (MTJ) have been important for many years and ferroelectric tunnel junctions (FTJ) are becoming ...
    • Shape-imposed anisotropy in antiferromagnetic complex oxide nanostructures 

      Bang, Ambjørn Dahle; Hallsteinsen, Ingrid; Chopdekar, Rajesh V.; Olsen, Fredrik Kjemperud; Slöetjes, Samuel Dingeman; Kjærnes, Kristoffer; Arenholz, Elke; Folven, Erik; Grepstad, Jostein (Journal article; Peer reviewed, 2019)
      In this study, we report on a shape-imposed magnetic anisotropy in micro- and nanostructures defined in antiferromagnetic (AF) LaFeO3 (LFO) thin films. Two distinct types of structures are investigated: embedded magnets ...
    • Synthesis and characterization of (111)-oriented BaTiO3 thin films 

      Bolstad, Torstein; Kjærnes, Kristoffer; Raa, Kristoffer S.; Takahashi, Ryota; Lippmaa, Mikk; Tybell, Per Thomas Martin (Journal article; Peer reviewed, 2019)
      The synthesis of (111)-oriented BaTiO3 thin films on Nb-doped SrTiO3 and bilayers of BaTiO3 and La0.7Sr0.3MnO3 on SrTiO3 are investigated. With increasing thickness the films are found to exhibit a decreasing out-of-plane ...
    • 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 ...
