Adelaide researchers verify new SQUID-array magnetic sensor design

Researchers in Adelaide have experimentally verified a SQUID-array design that replaces mismatched loop sizes with selected junction-free loops. The change allows the device to identify the absolute magnetic field while keeping a geometry optimised for sensitivity. The work was carried out in a cryogenic laboratory setting and points to improved superconducting magnetic field measurement.

Why now: A verified improvement in superconducting magnetic sensing is of interest to physics and quantum instrumentation communities.
