Journal ArticleDOI
Thickness dependence of superconducting critical current densityin vicinal YBa2Cu3O7−δ thick films
TL;DR: In this paper, the authors have deposited YBa2Cu3O7−δ (YBCO) films up to 30μm in thickness on flat and surface-miscut (100) SrTiO3 substrates with 5°, 10°, and 15° vicinal angles.
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
Optically transparent, mechanically durable, nanostructured superhydrophobic surfaces enabled by spinodally phase-separated glass thin films
Tolga Aytug,John T. Simpson,Andrew R. Lupini,Rosa M Trejo,Gerald Earle Jellison Jr,Ilia N. Ivanov,Stephen J. Pennycook,Daniel A. Hillesheim,Kyle O Winter,David K. Christen,Scott R. Hunter,J Allen Haynes +11 more
TL;DR: The formation and properties of atomically bonded, optical quality, nanostructured thin glass film coatings on glass plates are described, utilizing phase separation by spinodal decomposition in a sodium borosilicate glass system, demonstrating robust mechanical properties and superior abrasion resistance.
Journal ArticleDOI
Strong, asymmetric flux pinning by miscut-growth-initiated columnar defects in epitaxial YBa2Cu3O7-x films.
D. H. Lowndes,David K. Christen,C.E. Klabunde,Zhong Lin Wang,D. M. Kroeger,John D. Budai,Shen Zhu,David P. Norton +7 more
TL;DR: The results demonstrate that deliberately modified substrate surfaces may introduce technologically useful flux pinning in YBa[sub 2]Cu[sub 3]O[sub 7[minus][ital x]] films.
Journal ArticleDOI
Vortex Lattices in Cubic Superconductors
Vladimir G. Kogan,Predrag Miranovic,Lj. Dobrosavljević-Grujić,Warren E. Pickett,David K. Christen +4 more
TL;DR: In this paper, nonlocal corrections to London equations are employed to describe a variety of vortex lattices seen through neutron scattering in cubic crystals of V{sub 3}Si with large kappa.
