Recent Topics in High-T_c Superconductive Electronics

Abstract

This paper reports selected recent topics in high- T c superconductive electronics. Improved process technology for high- T c digital electronics, the development of a sampling oscilloscope, magnetic immunoassay using a high- T c superconducting quantum interference device (SQUID), scanning laser-SQUID for integrated circuits testing, terahertz radiation from high- T c superconductors, and optical control of vortices are reviewed.
