The angular dependence of Nb3Sn critical currents in transverse magnetic fields

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The dependence of critical currents of vapour-deposited and diffusion-processed Nb3Sn tapes on the magnitude and direction of magnetic field perpendicular to the current is experimentally investigated. By comparing the experimental results with theoretical considerations we conclude that the form of grains in the vapour-deposited samples is almost sinusoidal, whereas for the diffusion-processed ones it is more ellipsoidal. For both kinds of tapes, detailed structural microanalysis (electron microscopy, scanning electron microscopy, optical microscopy) of the substrate and the Nb3Sn tapes has been performed in order to explain the existence and the character of the above mentioned dependences from the processes of the grain formation.
