JOSEPHSON EFFECTS IN CERAMIC SUPERCONDUCTORS AND THEIR APPLICATION TO SQUID MAGNETOMETRY

Abstract
A brief review is given of Josephson Effects in high-Tc superconductors with specific reference to ceramic material properties and device applications. The development of liquid-nitrogen cooled rf and dc SQUIDs for ultrasensitive magnetometry will be described. Field sensitivities of better than 10-12 T / √Hz have already been achieved but 1 / f -noise becomes important at low frequencies.
