Mechanisms of weak thickness dependence of the critical current density in strong pinning ex situ metal-organic-deposition route YBa2Cu3O7-x coated conductors
S. I. Kim, A. Gurevich, X. Song +6
We report on the thickness dependence of the superconducting characteristics including critical current Ic, critical current density Jc, transition temperature Tc, irreversibility…
Very high upper critical fields in MgB2 produced by selective tuning of impurity scattering
A. Gurevich, S. Patnaik, V. Braccini +16
We report a significant enhancement of the upper critical field of different samples alloyed with nonmagnetic impurities. By studying films and bulk polycrystals w…
High Critical Current Density and Improved Irreversibility Field in Bulk MgB2 Made By A Scaleable, Nanoparticle Addition Route
J. Wang, Y. Bugoslavsky, A. Berenov +7
Bulk samples of MgB2 were prepared with 5, 10, and 15% wt.% Y2O3 nanoparticles added using a simple solid-state reaction route. Transmission electron microscopy (TEM) showed a fine…
Core pinning by intragranular nanoprecipitates in polycrystalline MgCNi_3
L. D. Cooley, X. Song, J. Jiang +4
The nanostructure and magnetic properties of polycrystalline MgCNi_3 were studied by x-ray diffraction, electron microscopy, and vibrating sample magnetometry. While the bulk flux-…
Electronic anisotropy, magnetic field-temperature phase diagram and their dependence on resistivity in c-axis oriented MgB2 thin films
S. Patnaik, L. D. Cooley, A. Gurevich +16
An important predicted, but so far uncharacterized, property of the new superconductor MgB2 is electronic anisotropy arising from its layered crystal structure. Here we report on t…
Thin Film Magnesium Boride Superconductor with Very High Critical Current Density and Enhanced Irreversibility Field
C. B. Eom, M. K. Lee, J. H. Choi +22
The discovery of superconductivity at 39 K in magnesium diboride offers the possibility of a new class of low-cost, high-performance superconducting materials for magnets and elect…
