摘要:
A detecting coil 3 of a SQUID 10 is made of a superconductive film material having a critical temperature higher than the critical temperature of a superconductive film material used to form the Josephson junctions 1. It is thus possible properly to measure the sample even when its temperature is higher than the critical temperature of the Josephson junctions.
摘要:
To reduce the number of steps of manufacturing a DC superconducting quantum interference device (as will be shortly referred to as "DC-SQUID"), which is to be applied to a highly sensitive electromagnetic sensor, an ammeter, a displacement meter a high-frequency signal amplifier or the like, thereby to improve the production yield. At the time of manufacturing the DC-SQUID, the number of masks is reduced to reduce the number of total steps by simultaneously performing the steps of fabricating an input coil 3 and a feedback coil 2 and the step of fabricating an counter electrode 13 of the components including a pick-up coil 1, the feedback coil 2, the input coil 3, a Josephson junction 10, a washer coil 11 and the counter electrode.
