Spin texture on top of vortex avalanches in Nb/Al_2O_3/Co thin film heterostructures
R. F. Lopes, D. Carmo, F. Colauto +5
We report on magneto-optical imaging, magnetization, Hall effect and magneto-resistance experiments in Nb/Al_2O_3/Co thin film heterostructures. The magnetic field is applied perpe…
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…
Flux Penetration in Superconducting Strip with Edge-Indentation
J. I. Vestgarden, D. V. Shantsev, Y. M. Galperin +1
The flux penetration near a semicircular indentation at the edge of a thin superconducting strip placed in a transverse magnetic field is investigated. The flux front distortion du…
Enhanced critical current density of YBa2Cu3Ox films grown on Nd1/3Eu1/3Gd1/3Ba2Cu3Ox with nano-undulated surface morphology
R. L. Meng, T. H. Johansen, I. A. Rusakova +5
We report a simple and easily controllable method where a nano-undulated surface morphology of Nd1/3Eu1/3Gd1/3Ba2Cu3Ox (NEG) films leads to a substantial increase in the critical c…
Experiments in vortex avalanches
E. Altshuler, T. H. Johansen
Avalanche dynamics is found in many phenomena spanning from earthquakes to the evolution of species. It can be also found in vortex matter when a type II superconductor is external…
