Superconducting Multilayered Ribbon for MRI Scanners, Produced Using Solid-Phase Technology

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

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.
