Search for pressure induced superconductivity in CeFeAsO and CeFePO iron pnictides
Diego A. Zocco, Ryan E. Baumbach, James J. Hamlin +11
The CeFeAsO and CeFePO iron pnictide compounds were studied via electrical transport measurements under high-pressure. In CeFeAsO polycrystals, the magnetic phases involving the Fe…
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…
BaFe2As2 Surface Domains and Domain Walls: Mirroring the Bulk Spin Structure
Guorong Li, Xiaobo He, Ang Li +8
High-resolution scanning tunneling microscopy (STM) measurements on BaFe2As2-one of the parent compounds of the iron-based superconductors-reveals a (1x1) As-terminated unit cell o…
Doping and dimensionality effects on the core-level spectra of layered ruthenates
Haizhong Guo, Yi Li, Darwin Urbina +7
Core-level spectra of the Mn-doped Sr3Ru2O7 and Srn+1RunO3n+1 (n = 1, 2 and 3) crystals are investigated with X-ray photoelectron spectroscopy. Doping of Mn to Sr3Ru2O7 considerabl…
Surface and Bulk Structural Properties of Single Crystalline Sr3Ru2O7
Biao Hu, Gregory T. McCandless, Melissa Menard +4
We report temperature and thermal-cycling dependence of surface and bulk structures of double-layered perovskite Sr3Ru2O7 single crystals. The surface and bulk structures were inve…
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…
