Synthesis and pinning properties of the infinite-layer superconductor Sr0.9La0.1CuO
C. U. Jung, J. Y. Kim, Mun-Seog Kim +5
We report the high-pressure synthesis of the electron-doped infinite-layer superconductor Sr0.9La0.1CuO2 and its superconducting properties. A Rietveld analysis of X-ray powder dif…
Substitution for Cu in the electron-doped infinite-layer superconductor Sr0.9La0.1CuO2, Ni reduces Tc much faster than Zn
C. U. Jung, J. Y. Kim, Min-Seok Park +3
We report on the effect of substitution for Cu on Tc of electron-doped infinite-layer superconductors Sr0.9La0.1Cu1-xRxO2, R = Zn and Ni. We found that Tc was nearly constant until…
Superconducting properties of well-shaped MgB2 single crystal
Kijoon H. P. Kim, Jae-Hyuk Choi, C. U. Jung +11
We report measurements of the transport and the magnetic properties of high-quality, sub-millimeter-sized MgB2 single crystals with clear hexagonal-plate shapes. The low-field magn…
Pressure dependent thermoelectric power of MgB superconductor
E. S. Choi, W. Kang, J. Y. Kim +4
We have measured temperature dependence of thermoelectric power (TEP) on MgB superconductor under hydrostatic pressure. The sign and temperature dependence of TEP shows metalli…
X-ray Photoemission Study of MgB2
R. P. Vasquez, C. U. Jung, Min-Seok Park +3
A c-axis oriented thin film and a high density sintered pellet of MgB2 have been studied by x-ray photoemission spectroscopy, and compared to measurements from MgO and MgF2 single…
X-ray Photoemission Study of the Infinite-Layer Cuprate Superconductor Sr0.9La0.1CuO2
R. P. Vasquez, C. U. Jung, J. Y. Kim +3
The electron-doped infinite-layer superconductor Sr0.9La0.1CuO2 is studied with x-ray photoemission spectroscopy (XPS). A nonaqueous chemical etchant is shown to effectively remove…
