This article relates generally to magnetometers employing DC superconducting quantum interference devices (SQUIDs) and, more particularly, to a technique for reducing the high frequency coupling between the SQUID and associated input circuitry. A reduction of the high frequency coupling between the SQUID loop and the input coil to the SQUID is accomplished by coupling the major part of the distributed capacitance of the input coil to a ground plane which is in turn coupled only weakly to the body of the SQUID.
