Infiltration and Top Seed Growth‐Textured YBCO Bulks With Multiple Holes

摘要: The recently reported hole-patterned YBa2Cu3Oy (Y123) bulks with improved superconducting properties are highly interesting from material quality and application variety points of view. It is well known that the core plain bulk superconductors needs to be fully oxygenated some defects like cracks, pores, voids must suppressed in order can trap a high magnetic field or carry current density. To minimize above defects, we have used combination standard ceramic processing an infiltration technique prepare regularly perforated superconductors. This process leads negligible shrinkage upon annealing uniform distribution Y211 inclusions. Texture was evidenced by neutron pole figure measurements. Flux mapping verify homogeneity samples investigate field-trapping ability. In addition, textured drilled were reinforced using resin metal impregnation influence different steps on hardness materials has been investigated.
