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…
