Arrangement for coupling an RF-squid magnetometer to a superconductive tank circuit
First Claim
Patent Images
1. An arrangement for coupling an rf-SQUID magnetometer to a superconductive tank circuit (1) comprising:
- a tank circuit having a circuit coil and a laminar capacitive structure which enclose the rf-SQUID magnetometer, said tank circuit consisting of superconductive thin-layer material; and
an rf-SQUID magnetometer (2) containing an rf-SQUID with a washer and a multiloop structures;
wherein the tank circuit (1) and the rf-SQUID magnetometer (2) are arranged planar to each other on the same substrate.

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.
