    • Effect of polar (111)-oriented SrTiO3 on initial perovskite growth 

      Hallsteinsen, Ingrid; Nord, Magnus Kristofer; Bolstad, Torstein; Vullum, Per Erik; Boschker, Jos Emiel; Longo, Paulo; Takahashi, Ryota; Holmestad, Randi; Lippmaa, Mikk; Tybell, Per Thomas Martin (Journal article, 2016)
      In crystalline thin film growth a prerequisite is substrate surfaces with a stable and uniform structure and chemical composition. Various substrate treatments were used to obtain atomically smooth, step-and-terrace ...

    • Magnetic domain configuration of (111)-oriented LaFeO3 epitaxial thin films 

      Hallsteinsen, Ingrid; Moreau, Magnus; Chopdekar, R.V.; Christiansen, Emil; Nord, Magnus Kristofer; Vullum, Per Erik; Grepstad, Jostein; Holmestad, Randi; Selbach, Sverre Magnus; Scholl, A; Arenholz, E; Folven, Erik; Tybell, Per Thomas Martin (Journal article; Peer reviewed, 2017)
      In antiferromagnetic spintronics control of the domains and corresponding spin axis orientation is crucial for devices. Here we investigate the antiferromagnetic axis in (111)-oriented LaFeO3/SrTiO3, which is coupled to ...

    • Magneto-dynamic properties of complex oxide—La0.7Sr0.3MnO3/SrTiO3— heterostructure interface 

      Singh, Suraj Kumar; Bolstad, Torstein; Hallsteinsen, Ingrid; Tybell, Per Thomas Martin; Wahlström, Erik (Journal article; Peer reviewed, 2019)
      We have studied the interface magnetodynamic properties of La0.7Sr0.3MnO3/SrTiO3 (111) heterostructures by Ferromagnetic resonance spectroscopy (FMR). In addition to the bulk FMR mode, the measurements indicate a mode ...

    • Structural investigation of epitaxial LaFeO3 thin films on (111) oriented SrTiO3 by transmission electron microscopy 

      Christiansen, Emil; Nord, Magnus Kristofer; Hallsteinsen, Ingrid; Vullum, Per Erik; Tybell, Per Thomas Martin; Holmestad, Randi (Journal article; Peer reviewed, 2015)
      We report on structural domains in LaFeO3 epitaxial thin films on (111) oriented SrTiO3 observed by transmission electron microscopy using low magnification dark field imaging and high resolution transmission electron ...
