  • Origin of enhanced conductivity in low dose ion irradiated oxides 
    Borgersen, Jon; Karsthof, Robert Michael; Rønning, Vegard; Vines, Lasse; Von Wenckstern, Holger; Grundmann, Marius; Kuznetsov, Andrej Yu.; Johansen, Klaus Magnus Håland (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Significant resistivity variations have previously been observed in oxides subjected to relatively low ion irradiation doses, nominally insufficient to generate the amount of bulk defects needed to explain the phenomena. ...
  • Valence state, lattice incorporation, and resulting magnetic properties of Ni in Zn/Co-based magnetic oxides 
    Ney, Verena; Henne, Bastian; de Souza, Mariano; Jantsch, Wolfgang; Johansen, Klaus Magnus Håland; Wilhelm, Fabrice; Rogalev, Andrei; Ney, Andreas (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)
    Ni incorporation has been studied in a comprehensive range of Zn/Co-based magnetic oxides to elucidate its valence state and lattice incorporation. The resulting structural and magnetic properties of a range of related ...
