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…
Superconducting tantalum nitride-based normal metal-insulator-superconductor tunnel junctions
S. Chaudhuri, I. J. Maasilta
We report the development of superconducting tantalum nitride (TaN) normal metal-insulator-superconductor (NIS) tunnel junctions. For the insulating barrier, we used both Al…
Fabrication of superconducting tantalum nitride thin films using infra-red pulsed laser deposition
Saumyadip Chaudhuri, Lucie Chandernagor, Manu Lahtinen +2
We report the successful fabrication of superconducting tantalum nitride (TaN) thin films using a pulsed laser deposition technique with 1064 nm radiation. Films with thickness $ \…
Niobium nitride-based normal metal-insulator-superconductor tunnel junction microthermometer
S. Chaudhuri, M. R. Nevala, I. J. Maasilta
We have successfully fabricated micron-scale Cu-AlO-Al-NbN normal metal-insulator-superconductor (NIS) tunnel junction devices, using pulsed laser deposition (PLD) for NbN f…
Suppression of magnetic flux avalanches and recovery of the critical state in superconducting NbN films
V. V. Yurchenko, A. J. Qviller, S. Chaudhuri +4
Thermo-magnetic instability (TMI) in superconductors is known to destroy the critical state via magnetic flux avalanches, and hence it deteriorates the ability of the superconducto…
Sub-micron normal-metal/insulator/superconductor tunnel junction thermometer and cooler using Nb
M. R. Nevala, S. Chaudhuri, J. Halkosaari +2
We have successfully fabricated Cu/AlOx-Al/Nb normal-metal/insulator/superconductor tunnel junction devices with a high value of the superconducting gap (up to mV), using…
Cooling, conductance and thermometric performance of non-ideal normal metal-superconductor tunnel junction pairs
S. Chaudhuri, I. J. Maasilta
We have investigated the effect of a difference in the tunnelling resistances of the individual normal metal-insulator-superconductor (NIS) tunnel junctions in a double junction SI…
