Bulk high-temperature superconductors (HTSs) that act as a trap field magnet establish a novel type of magnetic field source, which is significantly different from that of a permanent magnet or solenoid; therefore, they can be potentially used in magnetic-force-based applications. However, the primary issues related to the commercial use of the bulk HTS technology are established on the enhancement of trapped magnetic fields, as well as their reliability and reproducibility at temperatures achievable with off-the-shelf cryocoolers. This study presents experimental investigations on the strong trapped magnetic fields observed in commercial Y-Ba-Cu-O bulk HTSs produced as a double-sample stack, a cylindrical bulk, and a ring-shaped bulk. Consequently, a reliable and reproducible magnetic field of 9.5 T at 50 K was trapped in commercial Y-Ba-Cu-O assembled as a double-sample stack. In this case, shrink-fit encapsulation with either aluminum or stainless steel tube ensured equally e...

专为应用而设计的商用Y-Ba-Cu-O块状超导体的俘获场势

用作陷阱场磁体的高温高温超导体（HTS）建立了一种新型的磁场源，这种磁场源与永磁体或螺线管的磁场源明显不同。因此，它们可以潜在地用于基于磁力的应用中。但是，与大量HTS技术的商业使用有关的主要问题是建立在增强捕获的磁场，以及在现成的低温冷却器可达到的温度下其可靠性和可重复性方面。这项研究提供了对以双样品叠层，圆柱形块体和环形块体形式生产的商业Y-Ba-Cu-O块状高温超导体中观察到的强俘获磁场的实验研究。因此，可靠且可重现的磁场为9。将50 T下的5 T捕获在组装成双样品堆栈的商用Y-Ba-Cu-O中。在这种情况下，采用铝管或不锈钢管的热缩配合封装可确保同等...
