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…
RHEED Studies of Epitaxial Oxide Seed-Layer Growth on RABiTS Ni(001): The Role of Surface Structure and Chemistry
C. Cantoni, D. K. Christen, R. Feenstra +4
The epitaxial deposition of the first oxide buffer layer (seed layer) on biaxially textured Ni tape for coated conductors is a critical step that is dependent on the atomistic surf…
Unusual Hall Effect in Superconducting MgB Films: Analogy to High-T Cuprates
R. Jin, M. Paranthaman, H. Y. Zhai +3
We have investigated the temperature and magnetic field dependence of the Hall coefficient of two well-characterized superconducting MgB films (T=38.0 K) in both the nor…
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…
