The complex superstructure in Mg1-xAlxB2 at x~0.5
H. W. Zandbergen, M. Y. Wu, H. Jiang +3
Electron diffraction and high resolution microscopy have been performed on Mg1-xAlxB2 with x~0.5. This composition displays a superstructure with a repeat period of exactly 2c alon…
Temperature dependence of the structural parameters of the non-oxide perovskite superconductor MgCNi3
Q. Huang, T. He, K. A. Regan +5
We report the structural parameters of superconducting MgCxNi3 (x=0.96, TC=7.3 K) as a function of temperature, from 2 K to 295 K, determined by neutron powder diffraction profile…
The suppression of superconductivity in MgCNi3 by Ni-site doping
M. A. Hayward, M. K. Haas, A. P. Ramirez +5
The effects of partial substitution of Cu and Co for Ni in the intermetallic perovskite superconductor MgCNi3 are reported. Calculation of the expected electronic density of states…
Giant anharmonicity and non-linear electron-phonon coupling in MgB; A combined first-principles calculations and neutron scattering study
T. Yildirim, O. Gulseren, J. W. Lynn +12
We report first-principles calculations of the electronic band structure and lattice dynamics for the new superconductor MgB. The excellent agreement between theory and our i…
Thin Film Magnesium Boride Superconductor with Very High Critical Current Density and Enhanced Irreversibility Field
C. B. Eom, M. K. Lee, J. H. Choi +22
The discovery of superconductivity at 39 K in magnesium diboride offers the possibility of a new class of low-cost, high-performance superconducting materials for magnets and elect…
Loss of superconductivity and structural transition in Mg1-xAlxB2
J. S. Slusky, N. Rogado, K. A. Regan +8
The basic magnetic and electronic properties of most binary compounds have been well known for decades. Therefore the recent announcement of superconductivity at 39 K in the simple…
