“…In a HTSC junction of this sort the insulator is usually a thin PrBa 2 Cu 3 O 7 film that is 20 nm thick. 189 The superconducting properties of these junctions largely correspond to the classic RSJ (Resistively Shunted Junction) 190 model of a Josephson junction. The value of V m in these junctions is 0.2 mV.…”

This review article is a commemoration of the 30th anniversary of the discovery of YBa 2 Cu 3 O 7-d high-temperature superconductors (HTSCs). As a result of this discovery a family of (RE)Ba 2 Cu 3 O 7-d (RE stands for "rare earth") HTSCs has found great practical use. The review article consists of a brief history of how YBa 2 Cu 3 O 7-d was conceived and five sections describing the family of compounds: crystallography, phase diagrams, manufacturing techniques, main superconducting properties, and fields of application.

We developed a compact DC magnetometer using a high-temperature superconductor (HTS) superconducting quantum interference device (SQUID) to measure very weak magnetic signals from samples such as paramagnetic and diamagnetic materials. The samples were rotated in the DC magnetic field that was detected by a normal conductive pick-up coil. The detected signal was transferred to an input coil that was inductively coupled to the SQUID. To clarify the basic characteristics of this system, the magnetic signal from a magnetic material was measured by varying the sample position and rotation speed. Then, the magnetic signal from pure water was measured under the optimized condition and a very weak magnetic signal from pure water was successfully detected. Therefore, the developed system could be applied to various non-destructive evaluation systems.

Recent developments of electronic devices containing Josephson junctions (JJ) with high-T c superconductors (HTS) are reported. In particular, the fabrication process and the properties of superconducting quantum interference devices (SQUIDs) with a multilayer structure and ramp-edge-type JJs are described. The JJs were fabricated by recrystallization of an artificially deposited Cu-poor precursory layer. The formation mechanism of the junction barrier is discussed. We have fabricated various types of gradiometers and magnetometers. They have been actually utilized for several application systems, such as a non-destructive evaluation (NDE) system for deep-lying defects in a metallic plate and a reel-to-reel testing system for striated HTS-coated conductors.
