Nucleation and propagation of thermomagnetic avalanches in thin-film superconductors
J. I. Vestgården, T. H. Johansen, Y. M. Galperin
Stability of the vortex matter -- magnetic flux lines penetrating into the material -- in type-II superconductor films is crucially important for their application. If some vortice…
Metal frame as local protection of superconducting films from thermomagnetic avalanches
P. Mikheenko, J. I. Vestgaarden, S. Chaudhuri +3
Thermomagnetic avalanches in superconducting films propagating extremely fast while forming unpredictable patterns, represent a serious threat for the performance of devices based…
Ray optics in flux avalanche propagation in superconducting films
P. Mikheenko, T. H. Johansen, S. Chaudhuri +2
Experimental evidence of wave properties of dendritic flux avalanches in superconducting films is reported. Using magneto-optical imaging the propagation of dendrites across bounda…
Dendritic flux avalanches in superconducting films of different thickness
J. I. Vestgarden, Y. M. Galperin, T. H. Johansen
At low temperatures the critical state in superconducting films can be unstable with respect to thermomagnetic dendritic avalanches. By numerical simulations of disk-shaped superco…
Oscillatory regimes of the thermomagnetic instability in superconducting films
J. I. Vestgarden, Y. M. Galperin, T. H. Johansen
The stability of superconducting films with respect to oscillatory precursor modes for thermomag- netic avalanches is investigated theoretically. The results for the onset threshol…
Nonlocal electrodynamics of normal and superconducting films
J. I. Vestgarden, P. Mikheenko, Y. M. Galperin +1
Electrically conducting films in a time-varying transverse applied magnetic field are considered. Their behavior is strongly influenced by the self-field of the induced currents, m…
