Abstract Here, the anisotropy between the longitudinal and transverse directions of multi-filamentary Bi 2 Sr 2 Ca 2 Cu 3 O 10 + x tapes (“in plane ” anisotropy) is studied by transport and magnetization measurements. By minimally manipulating experimental data, we quantify it using one number associated with transport measurements, and two numbers based on magnetization curves. We propose that the simplest and most reliable number is that based on the magnetization loop width. We propose that the best way to evaluate the in-plane anisotropy is to measure the vertical width of the M vs. H loop, where H is applied along two mutually perpendicular directions lying on the wide face of the tape.

BSCCO 超导带中的面内各向异性:传输和磁力测量标准

摘要 这里,通过输运和磁化测量研究了复丝 Bi 2 Sr 2 Ca 2 Cu 3 O 10 + x 带(“平面内”各向异性)的纵向和横向之间的各向异性。通过最少地操纵实验数据,我们使用一个与传输测量相关的数字和两个基于磁化曲线的数字对其进行量化。我们建议最简单和最可靠的数字是基于磁化环宽度的数字。我们建议评估面内各向异性的最佳方法是测量 M 与 H 环的垂直宽度,其中 H 沿位于胶带宽面上的两个相互垂直的方向应用。
