A near-field scanning SQUID microwave microscope
Vladimir V Talanov, Nesco M Lettsome, Valery Borzenets +3
We developed a scanning DC SQUID microscope with novel readout electronics capable of wideband sensing RF magnetic fields from 50 to 200 MHz and simultaneously providing closed-loo…
Paramagnetic Meissner Effect in Multiply-Connected Superconductors
A. P. Nielsen, A. B. Cawthorne, P. Barbara +4
We have measured a paramagnetic Meissner effect in Nb-Al2O3-Nb Josephson junction arrays using a scanning SQUID microscope. The arrays exhibit diamagnetism for some cooling fields…
Reentrant AC magnetic susceptibility in Josephson-junction arrays: An alternative explanation for the paramagnetic Meissner effect
P. Barbara, F. M. Araujo-Moreira, A. B. Cawthorne +1
The paramagnetic Meissner effect (PME) measured in high granular superconductors has been attributed to the presence of -junctions between the grains. Here we present me…
