Since the discovery of high-temperature superconductivity
considerable progress has been made in research and
development of superconductive electronic devices. This fact
is reflected by the large variety of contributions to the
4th International Conference on Superconducting and Quantum
Effect Devices and their Applications - SQUID'91. This
comprehensive proceedings volume covers Josephson junctions,
SQUIDs, radiation detectors, flux-flow transitors.. The main
applications are contained in the chapters on biomagnetic
instrumentation, metrologym and rf-applications. The purpose
of this volume is to provide an up-to-date reference book on
thestatus of this rapidly changing and promising field of
electronic device research on the basis of low- and
high-temperature materials.
