Journal ArticleDOI
Low angle grain boundary transport in YBa2Cu3O7−δ coated conductors
Darren Verebelyi,David K. Christen,Ron Feenstra,Claudia Cantoni,Amit Goyal,Dominic F. Lee,M. Paranthaman,Paul N. Arendt,Raymond F. DePaula,J. R. Groves,C. Prouteau +10 more
TL;DR: In this article, an exponential dependence on the misorientation angle was shown for low-θ regime by evaluating single grain boundaries (GB) and biaxially aligned polycrystalline films utilizing both rolling-assisted biaXially textured substrates and ion-beam assisted deposition coated conductor architectures.
Journal ArticleDOI
Superconductivity in SrCuO2-BaCuO2 Superlattices: Formation of Artificially Layered Superconducting Materials
David P. Norton,Bryan C. Chakoumakos,John D. Budai,D. H. Lowndes,Brian C. Sales,James R. Thompson,David K. Christen +6 more
TL;DR: Pulsed-laser deposition was used to synthesize artificially layered high-temperature superconductors, and two new structural families, Ba2Srn–1,Cun+1 O2n+2+δ and Ba4Srn-1 Cun+3O2n-6+6-δ have been synthesized.
Journal ArticleDOI

TL;DR: In this article, the authors describe the fabrication of epitaxial, high-J c, biaxially aligned YBCO thick films on rolling-assisted bao-textured substrates (RABiTS).
Journal ArticleDOI
Enhanced current density Jc and extended irreversibility in single‐crystal Bi2Sr2Ca1Cu2O8 via linear defects from heavy ion irradiation
James R. Thompson,Yang Ren Sun,H. R. Kerchner,David K. Christen,Brian C. Sales,Bryan C. Chakoumakos,A. D. Marwick,L. Civale,J.O. Thomson +8 more
TL;DR: In this paper, the critical current density of a single crystal of the high-temperature superconductor Bi2Sr2Ca1Cu2O8 was improved by irradiation with high energy Sn ions.
Journal ArticleDOI
