Absence of a structural transition up to 40 Gpa in MgB2 and the relevance of magnesium non-stoichiometry
P. Bordet, M. Mezouar, M. Nunez-Regueiro +8
We report measurements on MgB2 up to ~40GPa. Increasing pressure yields a monotonous decrease of the lattice parameters and of the c/a ratio, but no structural transition down to p…
(13)C NMR investigation of the superconductor MgCNi_3 up to 800K
P. M. Singer, T. Imai, T. He +2
We report (13)C NMR characterization of the new superconductor MgCNi_3 (He et al., Nature (411), 54 (2001)). We found that both the uniform spin susceptibility and the spin fluctua…
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…
