Abstract
Low Tc superconducting quantum interference devices with asymmetric shunt resistances (SQUIDARs) have been numerically and experimentally investigated. Numerical simulations show that the flux to voltage transfer coefficient V? and magnetic flux noise S? are strongly dependent on both the asymmetry parameter ? and damping parameter ?= R/Rd, where R and Rd are the SQUID normal resistance and damping resistance, respectively. For small ? values, SQUIDARs show larger V? and smaller S? than symmetric devices. Asymmetric ...File in questo prodotto:
