TL;DR: Benefits of the critical current in self-field as well as excellent retention of this current in high applied magnetic fields were achieved in the thick films via incorporation of a periodic array of extended columnar defects, composed of self-aligned nanodots of nonsuperconducting material extending through the entire thickness of the film.

TL;DR: In this article, two buffer layer architectures were developed on rolled-Ni substrates using an electron beam evaporation technique, one consisting of an epitaxial laminate of CeO 2 /Pd/Ni and the other consisting of a YSZ/CeO 2/Ni.

TL;DR: In this article, it was shown that the critical current densities are determined by the grain boundary misorientation distributions (GBMDs), and that a percolative networks of low-angle boundaries with fractions consistent with the active cross-sectional area of the conductor exist in each of these conductors.
