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 کاملQuantum Left-handed metamaterial with superconducting quantum interference devices
A scheme of left-handed metamaterial (LHM) composed of superconducting quantum interference devices (SQUIDs) and conducting wires is proposed. The permeability of a probe field can be smoothly tuned over a wide range with another electromagnetic (coupling) field due to quantum interference effect. Similar to electromagnetically induced transparency (EIT) of atomic systems, the absorption of the...
متن کاملQuantum phase slip phenomenon in ultra-narrow superconducting nanorings
The smaller the system, typically - the higher is the impact of fluctuations. In narrow superconducting wires sufficiently close to the critical temperature T(c) thermal fluctuations are responsible for the experimentally observable finite resistance. Quite recently it became possible to fabricate sub-10 nm superconducting structures, where the finite resistivity was reported within the whole r...

متن کاملSuperconducting quantum interference devices based on YBaCuO nanobridges
Direct current SQUIDs based on YBaCuO thin film nanobridges have been investigated. Critical current densities Jc of the devices are up to 3310 6 A/cm at T577 K and show a temperature dependence of (12T/Tc) . High values of the voltage-flux modulation are observed ~8 mV peak to peak at 77 K, 45 mV at 4.2 K!. The temperature dependence of the SQUID modulation is found to be essentially different...
