MgB2 Energy Gap Determination by Scanning Tunneling Spectroscopy
T. W. Heitmann, S. D. Bu, D. M. Kim +13
We report scanning tunneling spectroscopy (STS) measurements of the gap properties of both ceramic MgB2 and c-axis oriented epitaxial MgB2 thin films. Both show a temperature depen…
Core pinning by intragranular nanoprecipitates in polycrystalline MgCNi_3
L. D. Cooley, X. Song, J. Jiang +4
The nanostructure and magnetic properties of polycrystalline MgCNi_3 were studied by x-ray diffraction, electron microscopy, and vibrating sample magnetometry. While the bulk flux-…
Low Temperature Fabrication of MgB2
N. Rogado, M. A. Hayward, K. A. Regan +4
We report the fabrication of MgB2 with bulk superconducting properties by conventional solid state methods at temperatures as low as 550 C. Mg deficiencies of the type Mg1-xB2 were…
Direct observation of nm-scale Mg- and B-oxide phases at grain boundaries in MgB2
R. F. Klie, J. C. Idrobo, N. D. Browning
Here we describe the results of an atomic resolution study of the structure and composition of both the interior of the grains, and the grain boundaries in polycrystalline MgB2. We…
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…
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…
