Strongly nonequilibrium flux flow in the presence of perforating submicron holes
D. Babic, J. Bentner, C. Suergers +1
We report on the effects of perforating submicron holes on the vortex dynamics of amorphous Nb0.7Ge0.3 microbridges in the strongly nonequilibrium mixed state, when vortex properti…
Vortex dynamics in the presence of a line of submicron holes along a superconducting microbridge
J. Bentner, D. Babic, C. Suergers +1
We measured and compared the electric field vs current density characteristics in the vortex state of two amorphous Nb0.7Ge0.3 microbridges, with and without a line of submicron ho…
Spontaneous supercurrent induced by ferromagnetic pi-junctions
A. Bauer, J. Bentner, M. Aprili +4
We present magnetization measurements of mesoscopic superconducting niobium loops containing a ferromagnetic (PdNi) pi-junction. The loops are prepared on top of the active area of…
Superconductivity on the localization threshold and magnetic-field-tuned superconductor-insulator transition in TiN films
T. I. Baturina, D. R. Islamov, J. Bentner +3
Temperature- and magnetic-field dependent measurements of the resistance of ultrathin superconducting TiN films are presented. The analysis of the temperature dependence of the zer…
Flux Flow Instabilities in Microstructured Amorphous Nb0.7Ge0.3 Thin Films
D. Babic, J. Bentner, C. Suergers +1
We report measurements of the electric field vs. current density [E(J] characteristics in the mixed state of amorphous Nb0.7Ge0.3 microbridges. Close to the transition temperature…
