The current-voltage characteristics of N vertically stacked Nb-based long Josephson junctions (N=1,2,3) are measured. For a single junction in the stack, we observe the splitting of the flux-flow mode into M modes, each of them being characterized by

The authors have deposited Nb/Al-AlO/sub x//Nb multilayers on Si substrates by DC and RF magnetron sputtering. To assist the fabrication of stacked tunnel junctions they investigated the layers by transmission electron microscopy and anodization spec

The design and performance of a planar microwave RF-SQUID (superconducting quantum interference device) read out by a cryogenic high-electron-mobility-transistor (HEMT) preamplifier are described. The SQUID sensor consists of a planar half-wavelength

Successful fabrication of stacked Nb-(Al/AlOx-Nb)n superconducting tunnel junctions with n=3 is reported. Coupling effects are visible in the three measured Fraunhofer patterns of the individual junctions. One of the patterns always shows a considera

We report on the design and performance of a planar microwave rf‐SQUID readout by a cryogenic preamplifier. The SQUID‐sensor consists of a planar half‐wavelength microstrip resonator, into which the SQUID‐loop is integrated. The pump frequenc

We developed a technique for fabrication of small stacked tunnel junctions with up to ten tunnel barriers in a stack. This technique allowed us to fabricate long stacked tunnel junctions in order to study the fluxon motion in closely spaced Josephson
