Proceedings ArticleDOI
Magnetic studies of current conduction and flux pinning in high‐Tc cuprates: Virgin, irradiated, and oxygen deficient materials
James R. Thompson,Yang Ren Sun,J. G. Ossandon,David K. Christen,H. R. Kerchner,Brian C. Sales,Bryan C. Chakoumakos,L. Civale,A. D. Marwick,F. Holtzberg +9 more
TL;DR: In this paper, single crystals of Y1Ba2Cu3O7 and Bi2Sr2Ca1Cu2O8 superconductors were studied using dc magnetic methods, which showed greatly increased irreversibility in the vortex state magnetization and enhanced intergrain current density Jc following irradiation.
Journal ArticleDOI
Tc-δ Relations in YB2Cu3O7-δ Thin Films: Effects of Oxygen Pressure During Growth
Ron Feenstra,David P. Norton,John D. Budai,David K. Christen,D. H. Lowndes,V. Matijasevic,Chang-Beom Eom,T. H. Geballe,E. S. Hellman,E. H. Hartford +9 more
TL;DR: In this paper, the Tc dependence on oxygen content was measured for YBa2Cu3O7-δ films grown with a variety of techniques (solid phase epitaxy, laser ablation, off-axis sputtering, co-evaporation) at oxygen pressures p(O2) ranging from 1.0 atm to 0.1 mTorr.

In Situ Growth of Epitaxial Superconducting Yba2Cu3O7-X Films on Insulating, Semiconducting and Ferroelectric K(Ta,Nb)O3 by Pulsed Laser Ablation
J. W. McCamy,David P. Norton,Douglas H. Lowndes,Lynn A. Boatner,David K. Christen,Ron Feenstra,E. Sonder +6 more
TL;DR: In this article, the first epitaxial growth experiments of YBa{sub 2}Cu{sub 3}O{sub 7-x} films on insulating, semiconducting and ferroelectric KTN single crystals by pulsed laser ablation were carried out.

s-Wave superconductivity in non-centrosymmetric Re_3W probed by magnetic penetration depth
Yuri L. Zuev,Valentina Kuznetsova,Ruslan Prozorov,M. D. Vannette,M. V. Lobanov,David K. Christen,James R. Thompson +6 more
TL;DR: In this paper, temperature dependence of the magnetic penetration depth in non-centrosymmetric superconductor Re_3W was measured on a powder sample, and the rf tunnel diode resonator technique, where a bulk polycrystalline sample was used.
Journal ArticleDOI
Heavy-Ion Damage to Magnesium Diboride Films: Electrical Transport-Current Characterization
H. R. Kerchner,Claudia Cantoni,Mariappan Parans Paranthaman,David K. Christen,Hans M. Christen,James R. Thompson,Dean J. Miller +6 more
TL;DR: The use of magnesium diboride in superconducting magnets, transmission lines, or other large-scale applications depends on the transport-current characteristics of this material in magnetic field, and how they compare to the properties of conventional and high-temperature superconductors.
