(HP22). With a regrettable delay of several months we like to attract the attention of our readers to the " Special Section on Recent Progress in Superconducting Analog Devices and their Applications " published in the March 2009 issue (No. 3) vol. E92-C, of the Japanese IEICE Transactions on Electronics. Access to full text (PDF) articles requires logging(More)
SUMMARY Effect of an addition of a cooled step-up transformer to a flux locked loop (FLL) circuit was studied to reduce indirect rf interference to HTS-dc-SQUID. First, we demonstrated that a noise level of an HTS-dc-SQUID system using the FLL circuit with single room-temperature transformer could be easily degraded by radiation of rf electromagnetic wave(More)
SUMMARY High-T c superconducting quantum interference device (SQUID) is an ultra-sensitive magnetic sensor. After the discovery of the high-T c superconducting materials, the performance of the high-T c SQUID has been improved and stabilized. One strong candidate for application is a detection system of magnetic foreign matters in industrial products. There(More)
