Thermoelectric radiation detector based on superconductor/ferromagnet systems
T. T. Heikkilä, R. Ojajärvi, I. J. Maasilta +3
We suggest a new type of an ultrasensitive detector of electromagnetic fields exploiting the giant thermoelectric effect recently found in superconductor/ferromagnet hybrid structu…
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…
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…
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…
Effect of a thin AlO_x layer on transition-edge sensor properties
Kimmo M. Kinnunen, Mikko R. J. Palosaari, Ilari J. Maasilta
We have studied the physics of transition-edge sensor (TES) devices with an insulating AlOx layer on top of the device to allow implementation of more complex detector geometries.…
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…
