Magnetic imaging of moat-guarded superconducting electronic circuits
Abstract
Superconducting electronic circuits surrounded by various configurations of holes in the superconducting ground plane have been imaged using a high resolution scanning superconducting quantum interference device (SQUID) microscope. These data demonstrate that in the weak field limit continuous moats trap flux more effectively to protect the circuits than small holes in the same configuration.© 1995 American Institute of Physics.
