Description
By using a cryogenic current comparator with a ferromagnetic core, optimum matching for high-source resistances of up to about 400 kΩ for a commercially available rf SQUID is achieved. This extends the use of SQUID instruments considerably, especially for applications where the source resistance exceeds 10-1 Ω
