David C. Larbalestier,L. D. Cooley,M.O. Rikel,A. A. Polyanskii,Jianyi Jiang,Satyabrata Patnaik,X. Y. Cai,D.M. Feldmann,Alex Gurevich,A.A. Squitieri,M.T. Naus,C. B. Eom,Eric E. Hellstrom,Robert J. Cava,K. A. Regan,N. Rogado,Michael A. Hayward,T. He,Joanna S.G. Slusky,Peter G. Khalifah,K. Inumaru,M. K. Haas +21 more
TL;DR: The combined magnetization, magneto-optical, microscopy and X-ray investigations show that the supercurrent density is mostly determined by flux pinning, rather than by the grain boundary connectivity, suggesting that this new superconductor class is not compromized by weak-link problems.
Journal ArticleDOI
Strongly linked current flow in polycrystalline forms of the new superconductor MgB2
David Larbalestier,M.O. Rikel,L.D. Cooley,A. A. Polyanskii,Jianyi Jiang,Satyabrata Patnaik,X.Y. Cai,D.M. Feldmann,Alex Gurevich,A.A. Squitieri,M.T. Naus,Chang-Beom Eom,Eric E. Hellstrom,Robert J.

TL;DR: In this paper, the discovery of superconductivity at 39 K in MgB2 has raised many issues, such as whether this new superconductor resembles a high-temperature cuprate super-conductor or a low-treme metallic super-conductors in terms of its current carrying characteristics in applied magnetic fields.
Journal ArticleDOI
High critical current density and enhanced irreversibility field in superconducting MgB2 thin films
C. B. Eom,Mk K. Lee,Jh H. Choi,Lj J. Belenky,Xueyan Song,L. D. Cooley,Mt T. Naus,Satyabrata Patnaik,Jianyi Jiang,M.O. Rikel,A. A. Polyanskii,Alex Gurevich,Xy Y. Cai,Sd D. Bu,Se E. Babcock,Ee E.

TL;DR: It is shown that MgB2 thin films that are alloyed with oxygen can exhibit a much steeper temperature dependence of H*(T) than is observed in bulk materials, yielding an H* value at 4.2 K greater than 14 T.

TL;DR: In this paper, it was shown that MgB_2 thin films can exhibit a much steeper temperature dependence of H*(T) than is observed in bulk materials, yielding H *(4.2 K) above 14 T.
Journal ArticleDOI
Loss of superconductivity with the addition of Al to MgB2 and a structural transition in Mg1-x AlxB2.
Joanna S.G. Slusky,N. Rogado,K. A. Regan,Michael A. Hayward,Peter G. Khalifah,T. He,K. Inumaru,Sergio Paulo Martins Loureiro,M. K. Haas,H. W. Zandbergen,Robert J. Cava +10 more
TL;DR: It is shown that the addition of electrons to MgB2, through partial substitution of Al for Mg, results in the loss of superconductivity, reflected in the partial collapse of the spacing between boron layers near an Al content of 10 per cent.
