Proceedings ArticleDOI
Limits to critical currents in high-temperature superconductors: What we can learn from tailored defects
David K. Christen,James R. Thompson,H. R. Kerchner,Brian C. Sales,Bryan C. Chakoumakos,L. Civale,A. D. Marwick,F. Holtzberg +7 more
TL;DR: In this paper, the authors consider factors that limit the loss-free conduction of electric current in the vortex state of high-temperature superconductors (HTS) and estimate the maximum possible critical current densities arising from optimally sized linear defects that pin each vortex core over its entire length.
Journal ArticleDOI
Decomposition of the Hall angle in the mixed state of superconductors
TL;DR: In this article, the authors show that the TDGL approach qualitatively explains the observed decomposition, and upon comparing with their data and several other published data, they find rough quantitative agreement as well.
Journal ArticleDOI
Magnetic Flux Pinning in YBa2Cu3O7 Films
H. R. Kerchner,Ron Feenstra,J.O. Thomson,J.O. Thomson,James R Thompson,James R Thompson,David K. Christen,S.T. Sekula,Lynn A. Boatner +8 more
TL;DR: In this paper, the magnetic hysteresis was studied for YBa 2 Cu 3 O 7 films of different epitaxial orientations on single-crystal SrTiO 3 and KTaO 3 substrates.
Journal ArticleDOI
Anisotropic electrical resistivity of YBCO/PBCO superlattice films grown on miscut substrates
H. R. Kerchner,C.E. Klabunde,David K. Christen,John D. Budai,D. H. Lowndes,David P. Norton,J. O. Thomson +6 more
TL;DR: In this paper, anisotropic electrical resistivity of epitaxial superlattice films of YBa{sub 2}Cu{sub 3}O{sub 7-delta}}/PrBa[sub 2]Cu[sub 3]O{ sub 7-{epsilon}} grown in situ by laser ablation on SrTiO(sub 3) surfaces aligned slightly away from the (100) direction is studied.
Journal ArticleDOI
Diffusion Mechanism of Cations and Anions in Cation-Exchange Process for Fabrication of High-Tc Superconducting HgBa2CaCu2O6+δ Films
TL;DR: In this article, the diffusion mechanism of Hg and Tl cations in cation-exchange process that has been used successfully for fabrication of high-Tc superconducting films was investigated.
