Journal ArticleDOI
Epitaxial yttria-stabilized zirconia on biaxially-textured (001) Ni for YBCO coated conductor
Chan Park,David P. Norton,Dominic F. Lee,Darren Verebelyi,Amit Goyal,David K. Christen,John D. Budai +6 more
TL;DR: The epitaxial YSZ layer grown on the Ni (001) surface was used as a single buffer layer for a high temperature superconducting coated conductor architecture, yielding YBa 2 Cu 3 O 7 films with critical current density of 1 MA/cm 2 at 77 K as mentioned in this paper.
Journal ArticleDOI
Critical currents, magnetic relaxation and pinning in NdBa 2 Cu 3 O 7-δ films with BaZrO 3 -generated columnar defects
Anota O Ijaduola,Sung Hun Wee,Amit Goyal,Patrick M Martin,Jing Li,James R. Thompson,David K. Christen +6 more
TL;DR: In this article, the critical current density Jc and the magnetic relaxation properties have been studied for a set of NdBa2Cu3O7−δ (NdBCO) films doped with BaZrO3 (BZO) nanoparticles to form columnar defects.
Journal ArticleDOI
Fabrication and physical properties of large-area HgBa2CaCu2O6 superconducting films
Y. Y. Xie,Judy Z. Wu,Tolga Aytug,A. A. Gapud,David K. Christen,Darren Verebelyi,Kyujeong Song +6 more
TL;DR: In this article, uniform zero-resistance Tc values of HgBa2 CaCu2 O6 (Hg-1212) superconducting thin films with their dimensions as large as ½ inch × ½ inch have been achieved using a cation exchange process.
Journal ArticleDOI
Epitaxial growth of MgO/TiN multilayers on Cu
Kyunghoon Kim,Kyunghoon Kim,David P. Norton,David K. Christen,Claudia Cantoni,Mariappan Parans Paranthaman,Tolga Aytug +6 more
TL;DR: In this article, the growth of epitaxial MgO/TiN multilayer films on (001) Cu has been investigated and shown to be a diffusion barrier to both copper and oxygen.
Journal ArticleDOI
Upper-critical fields of YBa2Cu3O7- delta epitaxial thin films with variable oxygen deficiency delta.
E. C. Jones,David K. Christen,James R. Thompson,J. G. Ossandon,Ron Feenstra,Julia M. Phillips,Michael P. Siegal +6 more
TL;DR: 3D scaling showed better convergence than the 2D scaling, and the transitions were not adequately described by either scaling for [ital T][sub [ital c]] off the 90-K plateau; it is speculated that this is due to an extrinsic broadening of the transitions.
