A direct probe of the variability of Coulomb correlation in Fe-pnictide superconductors
P. Vilmercati, C. Parks Cheney, F. Bondino +9
We use core-valence-valence (CVV) Auger spectra to probe the Coulomb repulsion between holes in the valence band of Fe pnictide superconductors. By comparing the two-hole final sta…
Itinerant electrons, local moments, and magnetic correlations in pnictides high temperature superconductors
P. Vilmercati, A. Fedorov, F. Bondino +11
A direct and element-specific measurement of the local Fe spin moment has been provided by analyzing the Fe 3s core level photoemission spectra in the parent and optimally doped Ce…
Electronic Structure of CeFeAsO1-xFx (x=0, 0.11/x=0.12) compounds
F. Bondino, E. Magnano, C. H. Booth +14
We report an extensive study on the intrinsic bulk electronic structure of the high-temperature superconductor CeFeAsO0.89F0.11 and its parent compound CeFeAsO by soft and hard x-r…
Probing Local Variations of Superconductivity on the Surface of Ba(Fe1-xCox)2As2 Single Crystals
T. -H. Kim, R. Jin, L. R. Walker +9
The spatially resolved electrical transport properties have been studied on the surface of optimally-doped superconducting Ba(Fe1-xCox)2As2 single crystal by using a four-probe sca…
Pressure effects on the electron-doped high Tc superconductor BaFe(2-x)Co(x)As(2)
K. Ahilan, J. Balasubramaniam, F. L. Ning +6
Application of pressures or electron-doping through Co substitution into Fe sites transforms the itinerant antiferromagnet BaFe(2)As(2) into a superconductor with the Tc exceeding…
