Journal ArticleDOI
Laser-ablated epitaxial LaAlO3 buffer layers on biaxially textured Ni substrates for superconducting tapes

TL;DR: In this article, a new epitaxial buffer layer configuration on biaxially textured Ni substrates for high temperature superconducting films is presented, and the epitaxy and crystal quality of these layers were investigated using X-ray diffraction including θ /2 θ and pole figure analysis, which showed that the consistency of the SrTiO 3 orientation requires further optimization.
Journal ArticleDOI
Magnetic field orientation dependence of flux pinning in (Gd,Y)Ba2Cu3O7―x coated conductor with tilted lattice and nanostructures
Yanwen Zhang,Eliot D. Specht,Claudia Cantoni,David K. Christen,James R Thompson,James R Thompson,John W Sinclair Iv,Amit Goyal,Yuri L. Zuev,Tolga Aytug,Mariappan Parans Paranthaman,Yimin Chen,Venkat Selvamanickam +12 more
TL;DR: In this paper, the authors studied the dependence of the critical current density (Jc) on the orientation of an applied magnetic field on a prototype (Gd,Y)Ba2Cu3O7−x (gdYBCO) coated conductor fabricated by MOCVD on an IBAD-MgO template.
Journal ArticleDOI
Near-isotropic performance of intrinsically anisotropic high-temperature superconducting tapes due to self-assembled nanostructures
TL;DR: In this article, the authors report material and operating parameter conditions where prototype HTS tape conductors exhibit critical current characteristics that are essentially field-orientation independent, and the effect can be described by a simple model for the field dependence of critical current density, generalized for anisotropic electronic response.

Buffer layers and articles for electronic devices
TL;DR: In this paper, materials for depositing buffer layers on biaxially textured and untextured metallic and metal oxide substrates for use in the manufacture of superconducting and other electronic articles are described.
