A Magnetization and Microwave Study of Superconducting MgB2
A. Dulcic, D. Paar, M. Pozek +5
We report magnetic field dependent magnetization and microwave impedance measurements on a MgB2 superconductor prepared by high pressure synthesis. We find that the upper critical…
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…
Far-infrared transmission studies of c-axis oriented superconducting MgB2 thin film
J. H. Jung, K. W. Kim, H. J. Lee +7
We reported far-infrared transmission measurements on a c-axis oriented superconducting MgB thin film in the frequency range of 30 250 cm. We found that these m…
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…
