ABSTRACT:
A SQUIDs magnetometer has three planar SQUID's which are fabricated on substrates mounted on three nonparallel surfaces of a member. Each SQUID is connected to a flux-locked loop drive circuit, and each SQUID has a main coil which is formed on the respective substrate and is threaded by the flux of an external magentic field which is being measured.
