Description

technical field [0001] The present invention relates to a measuring device for the critical current characteristic of the second generation high temperature superconducting strip, in particular to a device for measuring the critical current characteristic of the yttrium oxide YBCO superconducting strip in different temperature ranges, different background magnetic fields and magnetic field directions . Background technique [0002] In 1991, Fujikura of Japan used ion beam assisted deposition (IBAD) to obtain a layer of highly textured yttrium-stabilized zirconia ( YSZ) film, and then pulsed laser deposition (PLD) process was used to epitaxially deposit yttrium oxide YBCO on the baseband coating, announcing the advent of the second generation of high-temperature superconducting tape. Subsequently, the Los Alamos Laboratory (LANL) in the United States optimized these processes and announced in 1995 that the superconducting critical current density at 77K temperature reached 1...
