Abstract

An arrangement for coupling an rf-SQUID magnetometer to a superconductive tank circuit on a substrate is constructed in such a way that the two components are fully integrated into each other. Such integration increases the quality of the tank circuit by a factor of 2 to 3 as opposed to an arrangement obtainable by the flip-chip technology. Furthermore, the integrated arrangement permits simple assessment of coupling "k" between the SQUID and the tank circuit.
