Superconductive Thin Film Material for Electronic Devices Usable at Temperatures of Over 100 K

摘要

Superconductivity Research Laboratory, International Superconductivity Technology Center has developed a copper oxide superconductive thin film material for electronic devices that is usable at temperatures of over 100 K. Also, with the cooperation of Hitachi, Ltd. Basic Research Laboratory, a prototype superconductive quantum interference device (SQUID) (Note 1) was made and succeeded in demonstrating excellent performance including operation at a liquefied natural gas temperature of 110 K.
