Superconducting properties of Nb thin films deposited on porous silicon templates
M. Trezza, S. L. Prischepa, C. Cirillo +9
Porous silicon, obtained by electrochemical etching, has been used as a substrate for the growth of nanoperforated Nb thin films. The films, deposited by UHV magnetron sputtering o…
Picovoltmeter for probing vortex dynamics in a single weak-pinning Corbino channel
T. W. Heitmann, K. Yu, C. Song +4
We have developed a picovoltmeter using a Nb dc Superconducting QUantum Interference Device (SQUID) for measuring the flux-flow voltage from a small number of vortices moving throu…
Asymmetric weak-pinning superconducting channels: vortex ratchets
K. Yu, T. W. Heitmann, C. Song +4
The controlled motion of objects through narrow channels is important in many fields. We have fabricated asymmetric weak-pinning channels in a superconducting thin-film strip for c…
Long-range nonlocal flow of vortices in narrow superconducting channels
I. V. Grigorieva, A. K. Geim, S. V. Dubonos +5
We report a new nonlocal effect in vortex matter, where an electric current confined to a small region of a long and sufficiently narrow superconducting wire causes vortex flow at…
Enhancement of the superconducting transition temperature in Nb/Permalloy bilayers by controlling the domain state of the ferromagnet
A. Yu. Rusanov, M. Hesselberth, J. Aarts +1
In (S/F) hybrids the suppression of superconductivity by the exchange field h_ex of the ferromagnet can be partially lifted when different directions of h_ex are sampled simultaneo…
Depairing currents in superconducting films of Nb and amorphous MoGe
A. Yu. Rusanov, M. B. S. Hesselberth, J. Aarts
We report on measuring the depairing current J_{dp} in thin superconducting films as a function of temperature. The main difficulties in such measurements are that heating has to b…
