The Role of Nonlocality in the Pinning Properties of Borocarbides Materials
A. V. Silhanek, J. R. Thompson, L. Civale +2
An experimental review on the influence of nonlocal electrodynamics in the vortex pinning properties of non-magnetic borocarbide superconductors is presented. We show that the pinn…
Reply to the comment cond-mat/0308067
H. J. Kang, Pengcheng Dai, J. W. Lynn +6
Mang et al. report the observation of a cubic (Nd,Ce)2O3 impurity phase grown epitaxially in annealed samples of electron-doped Nd2-xCexCuO4 (NCCO) and argue that our observed magn…
On the Influence of a Non-Local Electrodynamics in the Irreversible Magnetization of Non-Magnetic Borocarbides
A. V. Silhanek, L. Civale, J. R. Thompson +4
We present an overview of the temperature, field and angular dependence of the irreversible magnetization of non-magnetic borocarbides (Y;Lu) Ni_2 B_2 C. We show that nonlocal elec…
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…
Slater Transition in the Pyrochlore Cd2Os2O7
D. Mandrus, J. R. Thompson, R. Gaal +7
Cd2Os2O7 crystallizes in the pyrochlore structure and undergoes a metal-insulator transition (MIT) near 226 K. We have characterized the MIT in Cd2Os2O7 using X-ray diffraction, re…
