Abstract

A detecting coil of a SQUID is made of a superconductive film material having a critical temperature higher than a critical temperature of a superconductive film material composing a Josephson junction part. It is possible to measure the sample even when its temperature is higher than the critical temperature of the Josephson junction section by increasing the critical temperature of the detecting coil than that of the Josephson junction section.
