    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: The present invention relates to a detecting apparatus for detecting a magnetic minute substance. The detecting apparatus of the present invention can detect continually at a high sensitivity an entity of fine particle, without destroying an object to be inspected. The detecting apparatus comprises a magnetic field generator and a magnetic sensor. The magnetic field generator generates a magnetic field having a right angle to the traveling direction of the object to be inspected. The magnetic sensor includes a SQUID for inspecting a drift of the magnetic field that is parallel to the magnetic field.

    摘要: A superconducting thin film pattern (20) formed from an oxide superconducting thin film is formed on a sapphire substrate (10) having a step (11) via a CeO2 buffer layer, and the step (11) and superconducting thin film pattern (20) are formed such that the step (11) crosses a predetermined portion of a square thin film pattern (22) having an opening portion (23) at the central portion. Step-edge Josephson junctions (26, 27) are formed at the portion crossed by the step (11), and a SQUID is obtained. The sapphire substrate is relatively inexpensive, and a large substrate can be used.

    摘要: A flux transformer comprises a pickup coil 1, an input coil 2 and a pair of lines 3, 4. The line 4 contains a bridge part 4a intersecting the input coil 2. The pickup coil 1, input coil 2 and a pair of lines 3, 4 are formed of a first and a second oxide superconducting thin films 11, 13. Furthermore, the flux transformer comprises a non-superconducting thin film 12. The non-superconducting thin film 12 is disposed between the first and the second oxide superconducting thin films 11, 13 and is located in a domain wherein the line 4 intersects the input coil 2. A pattern of the first oxide superconducting thin film 11 corresponds to the pickup coil 1, the input coil 2 and the lines 3,4 except the bridge part 4a. The pattern of the second oxide superconducting thin film 13 corresponds to the input coil 2 except the domain where the non-superconducting thin film exits, the pickup coil 1 and the lines 3,4. Except in the domain where the non-superconducting thin film 12 exists, the second oxide superconducting thin film 13 are piled up directly atop the first oxide superconducting thin film 11 in all domains.

    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.

    摘要: A nondestructive testing equipment comprises a magnetic sensor located within a magnetic shield container. The magnetic sensor includes a SQUID that is a magnetic sensor having a very high sensitivity. A magnetically uniform inspection zone is formed in the magnetic shield container. While a rod-like material to be tested passes through the inspection zone at a uniform velocity, the magnetic sensor can detect an appreciable magnetic field variation that is caused by impurities or minor defects contained in the object to be tested.
