Abstract

A solid-phase technology is described for producing a superconducting multilayered ribbon with layers ~150 nm thick from a solid solution of titanium in niobium and an Nb–50% Ti alloy. The ribbon is 0.1 mm thick. Measurements of the critical current of the ribbons at perpendicular and parallel orientations of external magnetic field H relative to the plane of the layers reveals considerable anisotropy in magnetic fields Н > 1 T. This testifies to the pinning of superconducting vortices on the non-superconducting layers of the niobium solid solution. The critical current in a field of 5 T reaches 50 A per 1 mm of the ribbon width.

摘要

描述了一种固相技术，用于从钛在铌中的固溶体和 Nb–50% 钛合金中生产具有约 150 纳米厚层的超导多层带。色带厚 0.1 毫米。在外部磁场H相对于层平面的垂直和平行方向上的带临界电流的测量揭示了磁场Н > 1 T 的相当大的各向异性。 这证明了超导涡流在非超导层上的钉扎铌固溶体。5 T 场中的临界电流达到每 1 mm 带宽度 50 A。
