    • Anisotropy and domain formation in a dipolar magnetic metamaterial 

      Digernes, Einar Standal; Strømberg, Anders; Vaz, Carlos A. F.; Kleibert, Armin; Grepstad, Jostein; Folven, Erik (Journal article; Peer reviewed, 2021)

    • Fabrication of Si(111) crystalline thin film on graphene by aluminum-induced crystallization 

      Høiaas, Ida Marie; KIM, DONG CHUL; Weman, Helge (Journal article; Peer reviewed, 2016)
      We report the fabrication of a Si(111) crystalline thin film on graphene by the aluminum-induced crystallization (AIC) process. The AIC process of Si(111) on graphene is shown to be enhanced compared to that on an amorphous ...

    • Interplay between bulk and edge-bound topological defects in a square micromagnet 

      Slöetjes, Samuel Dingeman; Digernes, Einar; Olsen, Fredrik Kjemperud; Chopdekar, Rajesh V.; Retterer, Scott T.; Folven, Erik; Grepstad, Jostein (Journal article; Peer reviewed, 2018)
      A field-driven transformation of a domain pattern in a square micromagnet, defined in a thin film of La0.7Sr0.3MnO3, is discussed in terms of creation and annihilation of bulk vortices and edge-bound topological defects ...

    • Magnetic domain formation in ultrathin complex oxide ferromagnetic/antiferromagnetic bilayers 

      Bang, Ambjørn Dahle; Olsen, Fredrik Kjemperud; Slöetjes, Samuel Dingeman; Scholl, Andreas; Retterer, Scott T.; Vaz, Carlos; Tybell, Per Thomas Martin; Folven, Erik; Grepstad, Jostein (Journal article; Peer reviewed, 2018)
      In this study, we report on the magnetic domain formation in ultrathin blanket films and patterned micro- and nanostructures of ferromagnetic (FM) La0.7Sr0.3MnO3 single-layers and antiferromagnetic (AF)/ferromagnetic ...

    • 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 ...

    • Neel vector reorientation in ferromagnetic/antiferromagnetic complex oxide nanostructures 

      Bang, Ambjørn Dahle; Hallsteinsen, Ingrid; Olsen, Fredrik Kjemperud; Slöetjes, Samuel Dingeman; Retterer, Scott T; Scholl, Andreas; Arenholz, Elke; Folven, Erik; Grepstad, Jostein (Journal article; Peer reviewed, 2019)
      In this study, we report on a temperature-driven antiferromagnetic (AF) spin reorientation transition in micro- and nanostructures of AF/ferromagnetic (FM) LaFeO3/La0.7Sr0.3MnO3 thin film bilayers. Using a combination of ...

    • Selective area growth of AlGaN nanopyramid arrays on graphene by metal-organic vapor phase epitaxy 

      Munshi, A Mazid; Kim, Dong-Chul; Heimdal, Carl Philip J; Heilmann, Martin; Christiansen, Silke; Vullum, Per Erik; Van Helvoort, Antonius; Weman, Helge (Journal article; Peer reviewed, 2018)
      Wide-bandgap group III-nitride semiconductors are of special interest for applications in ultraviolet light emitting diodes, photodetectors, and lasers. However, epitaxial growth of high-quality III-nitride semiconductors ...

    • 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 ...

    • Tunable topological edge modes in Su-Schrieffer-Heeger arrays 

      Chaplain, G.J.; Gliozzi, A.S.; Davies, B.; Urban, David; Descrovi, Emiliano; Bosia, F.; Craster, R.V. (Peer reviewed; Journal article, 2023)
      A potential weakness of topological waveguides is that they act on a fixed narrow band of frequencies. However, by 3D printing samples from a photo-responsive polymer, we can obtain a device whose operating frequency can ...
