TL;DR: In this paper, a simple and practically scalable technique was used to produce long, nearly continuous vortex pins along the c-axis in YBa2Cu3O7?? (YBCO), in the form of self-assembled stacks of BaZrO3 (BZO) nanodots and nanorods.
Journal ArticleDOI

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.
Journal ArticleDOI
Enhancement of flux pinning in YBa2Cu3O7−δ thin films embedded with epitaxially grown Y2O3 nanostructures using a multi-layering process

TL;DR: In this paper, Nanodot arrays of Y2O3 were dispersed in thin films of YBa2Cu3O7−δ (YBCO) by growing alternating layers of these two species using a pulsed laser deposition method.
Journal ArticleDOI
Critical currents of ex situ YBa2Cu3O7- δ thin films on rolling assisted biaxially textured substrates : Thickness, field, and temperature dependencies
A.O. Ijaduola,James R Thompson,James R Thompson,Roeland Feenstra,David K. Christen,Albert A. Gapud,Xueyan Song +6 more
TL;DR: In this article, the critical current density of thin YBCO films has been studied magnetometrically, both as a function of applied field and temperature, with a central objective to determine the dominant source of vortex pinning in these materials.
Journal ArticleDOI
Evidence for extensive grain boundary meander and overgrowth of substrate grain boundaries in high critical current density ex situ YBa2Cu3O7−x coated conductors
D.M. Feldmann,David C. Larbalestier,Terry G. Holesinger,Ron Feenstra,Albert A. Gapud,Eliot D. Specht +5 more
TL;DR: In this article, electron backscatter diffraction combined with ion milling was used to map the evolution of the YBCO grain structure and compare it to the underlying template in several coated conductors.
