Abstract
High T.sub.c superconductor quantum interferometric devices are disclosed. Such devices are especially suited for detecting small changes and spatial variation in magnetic field. Such detection finds important application in NDE evaluation of metals, in the evaulation of magnetic susceptibilities and in magnetic resonance spectrometers.
