Higher harmonics of ac voltage response in narrow strips of YBa2Cu3O7 thin films: Evidence for strong thermal fluctuations
J. G. Ossandon, S. Sergeenkov, P. Esquinazi +1
We report on measurements of higher harmonics of the ac voltage response in strips of YBa2Cu3O7 thin films as a function of temperature, frequency and ac current amplitude. The thi…
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…
Vortex pinning in high-Tc materials via randomly oriented columnar defects, created by GeV proton-induced fission fragments
J. R. Thompson, J. G. Ossandon, L. Krusin-Elbaum +4
Extensive work has shown that irradiation with 0.8 GeV protons can produce randomly oriented columnar defects (CD's) in a large number of HTS materials, specifically those cuprates…
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…
