Research Data supporting "Optimisation of the processing parameters for fabricating high-quality joints between Y-Ba-Cu-O bulk superconductors dataset"

A dataset associated with the listed publication. Trapped field measurements taken as follows: The top and bottom faces of all of the YBCO samples were polished flat and parallel using 180 grit silicon carbide paper. The maximum trapped field at the top and bottom surface was measured initially using a hand-held Hall probe positioned approximately 0.5 mm above the sample surface. Subsequently, the trapped field profile across both the top and bottom surface of each single grain was measured using a rotating array of 19 Hall probes positioned approximately 1.5 mm above the surface of each sample. The samples had been field cooled at 77 K in an applied magnetic field of 1.4 T prior to trapped field measurement. The temperature of each sample was maintained at 77 K for the duration of each measurement.

本数据集与所列发表文献相关。相关俘获场（trapped field）测量流程如下：采用180目碳化硅砂纸将所有钇钡铜氧（YBCO）样品的上下表面研磨至平整且相互平行。初始阶段，通过置于样品表面上方约0.5 mm处的手持式霍尔探头，测量样品上下表面的最大俘获场。随后，通过布置在每个样品表面上方约1.5 mm处的19个旋转式霍尔探头阵列，测量每颗单晶粒样品上下表面的俘获场分布。所有样品在开展俘获场测量前，已在1.4 T的外加磁场中于77 K温度下完成场冷（field cooled）处理。每次测量全程均将样品温度维持在77 K。
