摘要：

Different sensors for weak magnetic signals were realized using thin high temperature superconducting films on different substrates including buffered silicon. Superconducting quantum interference devices (SQUIDs), magnetometers and planar gradiometers based on them as well as a new type of Hall-effect sensor with a superconducting antenna were tested with respect to signal resolution, band width and spatial resolution. To realize adapted systems for biomagnetic research or non-destructive evaluation common room temperature electronics have some disadvantages. Thus we tested discrete elements as well as special adapted integrated BiCMOS circuits placed near the sensors at 77 K. We demonstrate the status of the development: of such electronics.
