SQUID Concepts and Systems

“…The spectral density of the noise measured at 1Hz is shown vs. temperature in Fig.30. We see that in each case the, noise increases rapidly as the temperature approaches Tc, and that, at a given The best characterized rf SQUID reported so far is that of Zimmerman et al 93 They drilled a hole along the axis of a cylindrical pellet of YBCO, and cut a slot part way along a radius (Fig.29). The pellet was glued into an aluminum holder, also with a slot, and the assembly was immersed in LN.…”

Processing Techniques for the 93 K Superconductor Ba 2 YCu 3 O 7

“…A variety of electronic applications have been proposed for the new superconductors including high-speed chip interconnections (84, 85) or even active devices (86,87). Much of the excitement in this area comes from the fact that for the first time superconductivity 926 occurs at temperatures where it is practical to operate semiconductor devices.…”

SQUIDs: Principles, Noise, and Applications

“…The configuration is shown in Fig.20; the estimated inductance is 80pH. The best characterized rf SQUID reported so far is that of Zimmerman et al 93 They drilled a hole along the axis of a cylindrical pellet of YBCO, and cut a slot part way along a radius (Fig.21 ).
