    Sado, Pascal (Doctoral thesis / Doktoravhandling, 2023)
    Images taken of aurora are of key interest for research regarding space physics.To get as much material as possible, many imagers are positioned in key locations around the world, taking many images per year.Over the span ...
  • A Machine Protection Risk Management Method for Complex Systems 
    Andersson, Riccard (Doctoral thesis / Doktoravhandling, 2017)
    Accelerator-based research facilities play a key role in modern research, where they increasingly push the technical limits. At the same time, they aim at competing with industrial and nuclear research facilities in ...
  • Magnetic Bloch oscillations and domain wall dynamics in a near-Ising ferromagnetic chain 
    Bengaard Hansen, Ursula; Syljuåsen, Olav Fredrik; Jensen, Jens; Schaffer, Turi K.; Boehm, Martin; Andersen, Christopher R.; Ridriguez-Rivera, Jose A.; Christensen, Niels Bech; Lefmann, Kim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract When charged particles in periodic lattices are subjected to a constant electric field, they respond by oscillating. Here we demonstrate that the magnetic analogue of these Bloch oscillations are realised in a ...
  • Magnetic Bloch oscillations in CoNb2O6 
    Seland, Aleksander (Master thesis / Masteroppgave, 2017)
    The material CoNb2O6 has in recent times attracted much attention due to having rich physics in applied magnetic fields. This thesis explores whether or not it is possible to observe magnetic Bloch oscillations in CoNb2O6. ...
  • Magnetic decoration of Escherichia coli loaded with Palladium nanoparticles 
    Campana Perilla, Ana Lucia; Joudeh, Nadeem; Linke, Dirk; Mikheenko, Pavlo (Chapter / Bokkapittel / SubmittedVersion, 2021)
    Palladium (Pd) is a scarce metal, which is able to catalyze a variety of important chemical reactions. In the bulk form, Pd is anomalous paramagnetic, but in the form of nanoparticles, it has been reported as ferromagnetic. ...
  • Magnetic Excitations In The Iridate Sr2IrO4 
    Leonhardt, Andreas Karl (Master thesis / Masteroppgave, 2014)
    In this thesis we investigated magnetic excitations in the iridate compound Sr2IrO4. As a layered strongly correlated system it can be described by the two-dimensional one-band Hubbard model, describing interacting particles ...
