چکیده
Superconducting quantum interference devices (SQUIDs) that incorporate two superconductor/insulator/superconductor (SIS) Josephson junctions in a closed loop form the core of some most sensitive detectors magnetic and electric fields currently available. SQUIDs these applications are typically operated with finite voltage which generates microwave radiation through ac effect. This may impact system being measured. We describe here SQUID formed from strips normal metal (N) good electrical contact superconductor (S). Such SNS can be under bias performance comparable or potentially better than conventional SIS SQUIDs. However, they also permit novel mode operation is based on unusual interplay quasiparticle currents supercurrents junction. The new method allows measurements flux dependence critical current without applying across junction, enabling detection generating radiation.

Superconducting quantum interference device instruments and applications
Superconducting quantum interference devices SQUIDs have been a key factor in the development and commercialization of ultrasensitive electric and magnetic measurement systems. In many cases, SQUID instrumentation offers the ability to make measurements where no other methodology is possible. We review the main aspects of designing, fabricating, and operating a number of SQUID measurement syste...
متن کاملNanowire acting as a superconducting quantum interference device.
We present the results from an experimental study of the magnetotransport of superconducting wires of amorphous indium-oxide having widths in the range 40-120 nm. We find that, below the superconducting transition temperature, the wires exhibit clear, reproducible, oscillations in their resistance as a function of magnetic field. The oscillations are reminiscent of those that underlie the opera...
متن کاملMicrotesla MRI with a superconducting quantum interference device.
MRI scanners enable fast, noninvasive, and high-resolution imaging of organs and soft tissue. The images are reconstructed from NMR signals generated by nuclear spins that precess in a static magnetic field B0 in the presence of magnetic field gradients. Most clinical MRI scanners operate at a magnetic field B0 = 1.5 T, corresponding to a proton resonance frequency of 64 MHz. Because these syst...
متن کاملQuantum interference device made by DNA templating of superconducting nanowires.
The application of single molecules as templates for nanodevices is a promising direction for nanotechnology. We used a pair of suspended DNA molecules as templates for superconducting two-nanowire devices. Because the resulting wires are very thin, comparable to the DNA molecules themselves, they are susceptible to thermal fluctuations typical for one-dimensional superconductors and exhibit a ...
متن کاملScanning superconducting quantum interference device microscope in a dilution refrigerator
We report on a scanning superconducting quantum interference device microscope operating at temperatures down to 20 mK in a dilution refrigerator. The instrument is designed for studying quantum mechanical coherence effects in mesoscopic systems and investigating magnetic effects on a mesoscopic length scale in novel materials. We have demonstrated the low-temperature operating capabilities of ...
