    摘要： A soft magnetic material is a soft magnetic material including a composite magnetic particle (30) having a metal magnetic particle (10) mainly composed of Fe and an insulating coating (20) covering metal magnetic particle (10), and insulating coating (20) contains an iron phosphate compound and an aluminum phosphate compound. The atomic ratio of Fe contained in a contact surface of insulating coating (20) in contact with metal magnetic particle (10) is larger than the atomic ratio of Fe contained in the surface of insulating coating (20). The atomic ratio of Al contained in the contact surface of insulating coating (20) in contact with metal magnetic particle (10) is smaller than the atomic ratio of Al contained in the surface of insulating coating (20). Thus, iron loss can be reduced.

    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 sulfide-based inorganic solid electrolyte that suppresses the reaction between silicon sulfide and metallic lithium even when the electrolyte is in contact with metallic lithium, a method of forming the electrolyte, and a lithium battery's member and lithium secondary battery both incorporating the electrolyte. The electrolyte comprises Li, P, and S without containing Si. It is desirable that the oxygen content vary gradually from the electrolyte to the lithium-containing material at the boundary zone between the two members when analyzed by using an XPS having an analyzing chamber capable of maintaining a super-high vacuum less than 1.33×10−9 h Pa and that the oxygen-containing layer on the surface of the lithium-containing material be removed nearly completely. The electrolyte can be formed such that at least part of the forming step is performed concurrently with the step for etching the surface of the substrate by irradiating the surface with inert-gas ions.

    摘要： A magnetic sensor comprises a SQUID made of a superconducting thin film. The superconducting thin film has a washer pattern and a terminal portion. The washer pattern has a non-square one hole pattern and a pair of slit patterns. The hole pattern has rectangle shape and includes the center of the washer pattern. The slit patterns having a straight shape growing parallel to the long side of the hole pattern, from the outside edge of the washer pattern toward the inside of the washer pattern. This outside edge of the washer pattern is the nearest to the hole pattern. There is an artificial grain boundary in the domain that spacing between the hole pattern and the slit pattern is narrowest. There is no artificial grain boundary in the other domain at all.
