  • Dendritic flux avalanches in a superconducting MgB2 tape 
    Qureishy, Thomas; Laliena, Carlos; Martínez, Elena; Qviller, Atle Jorstad; Vestgården, Jørn Inge; Johansen, Tom Henning; Navarro, Rafael; Mikheenko, Pavlo (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Tapes of MgB2 with high critical current have a significant technological potential, but can experience operational breakdown due to thermomagnetic instabilities. Such events are routinely registered by magnetisation ...
  • Energy of dendritic avalanches in thin-film superconductors 
    Qureishy, Thomas; Vestgården, Jørn Inge; Qviller, Atle Jorstad; Fjellvåg, Asbjørn Slagtern; Meckbach, Johannes Maximilian; Torgovkin, Andrii; Johansen, Tom Henning; Ilin, Konstantin; Siegel, Michael; Maasilta, Ilari J.; Mikheenko, Pavlo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    A method for calculating stored magnetic energy in a thin superconducting film based on quantitative magneto-optical imaging is developed. Energy and magnetic moment are determined with these calculations for full hysteresis ...
  • Magneto-optical imaging of columnar YBCO films 
    Mikheenko, Pavlo; Yurchenko, Vitaliy; Tanner, John L.; Qviller, Atle Jorstad; Galperin, Yuri; Vestgården, Jørn Inge; Crisan, A; Johansen, Tom Henning (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    The columnar growth of superconducting films is a new approach that provides high density of evenly distributed extended defects on the nanometer scale. This growth can be activated by tightly-packed nanoparticles deposited ...
  • Magneto-optical investigation of complex flux dynamics in superconductors 
    Qviller, Atle Jorstad (Doctoral thesis / Doktoravhandling, 2012)
  • Nanosecond voltage pulses from dendritic flux avalanches in superconducting NbN films 
    Mikheenko, Pavlo; Qviller, Atle Jorstad; Vestgården, Jørn Inge; Chaudhuri, S.; Maasilta, IJ; Galperin, Yuri; Johansen, Tom Henning (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Combined voltage and magneto-optical study of magnetic flux flow in superconducting NbN films is reported. The nanosecond-scale voltage pulses appearing during thermomagnetic avalanches have been recorded in films partially ...
  • Scaling Behavior of Quasi-One-Dimensional Vortex Avalanches in Superconducting Films 
    Qviller, Atle Jorstad; Qureishy, Thomas; Xu, Y; Suo, H; Mozhaev, PB; Hansen, J.B.; Vestgården, Jørn Inge; Johansen, Tom Henning; Mikheenko, Pavlo (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Scaling behaviour of dynamically driven vortex avalanches in superconducting YBa2Cu3O7−δ films deposited on tilted crystalline substrates has been observed using quantitative magneto-optical imaging. Two films with different ...
