Irreversibility lines in [formula omitted] thin films with Ba–Nb–O nanorods

Abstract

We report vortex-Bose-glass-like irreversibility lines (IL) depending on both growth temperature and nominal content of a nanorod material in Er–Ba–Cu–O films containing nanorods. The IL was expanded to higher magnetic fields with decreasing growth temperature (Ts), while Tc decreased. Our findings indicate that Ts in the production process of coated conductors containing nanorods is an important determination factor of critical current performance under high magnetic fields.
