Pinning Action of Correlated Disorder against Equilibrium Properties of HgBaCaCuO: a Delicate Balance
J. R. Thompson, J. G. Ossandon, L. Krusin-Elbaum +5
We report significant alteration of the equilibrium properties of the superconductor HgBaCaCuO when correlated disorder in the form of randomly oriented columnar tr…

Current density and reversible magnetization of HgBa(2)Ca(2)Cu(3)O(x) superconductors containing randomly oriented columnar defects
J. R. Thompson, J. G. Ossandon, L. Krusin-Elbaum +5
Bulk polycrystalline HgBa(2)Ca(2)Cu(3)O(x) materials were irradiated with 0.8 GeV protons to form randomly oriented columnar defects, by induced fission of Hg-nuclei. Proton fluenc…

High temporal stability of supercurrents in MgB(2) materials
J. R. Thompson, M. Paranthaman, D. K. Christen +3
Fine grained polycrystalline samples of MgB(2) superconductor were synthesized from the elements to contain < 5 % of impurity phases, according to X-ray powder diffractometry. The…
