摘要： A method of producing a thin film of an inorganic solid electrolyte having a relatively high ionic conductance is provided. In the method, a thin film made of an inorganic solid electrolyte is formed, by a vapor deposition method, on a base member being heated. The thin film obtained through the heat treatment exhibits an ionic conductance higher than that of the thin film formed on the base member not being heated. The ionic conductance can also be increased through the steps of forming the thin film made of the inorganic solid electrolyte on the base member at room temperature or a temperature lower than 40° C. and then heating the thin film of the inorganic solid electrolyte.

摘要： This magnetic sensor comprises a flux transformer 2 having a superconducting thin film 2f formed on a sapphire substrate 2s, and a SQUID 1 disposed on the flux transformer 2 opposite thereto. In this magnetic sensor, since the sapphire substrate 2s, which can be obtained in a large size, is used for the flux transformer 2, even when the SQUID 1 is made smaller, the magnetic flux introduced from the flux transformer 2 into the SQUID 1 can be enhanced so as to increase the effective magnetic flux capturing area, whereby the detecting performance is improved, while the manufacturing cost can be reduced due to the smaller size of the SQUID 1.

摘要： A magnetic field sensor has a SQUID, which is made of thin film of oxide superconductor deposited on a substrate, and a magnetic flux guide that has a higher permeability than vacuum to increase the effective capture area. The flux guide is positioned and aligned over a hole that is surrounded with superconducting current loop formed in a washer thereof. The SQUID also has a pair of Josephson junction formed on the washer and a pair of opposite terminals for connecting the washer to an outer circuit. In the SQUID, a variation in magnetic flux passing through the hole is detected in a form of variation in output voltage.
