Evidence for a smooth superconductor to normal state transition for nonzero applied magnetic field in Sr0.9La0.1CuO2
T. Schneider, R. Khasanov, D. Di Castro +4
We present and analyze field cooled magnetization data, revealing for 0<H<5 T remarkable consistency with a magnetic field induced finite size effect. It is traced back to the fact…
Temperature and magnetic field dependent tunneling spectroscopy of PtIr/SrLaCuO point contact
L. Shan, H. Gao, Z. Y. Liu +5
Low barrier quasiparticle tunneling spectroscopy on SrLaCuO has been studied with PtIr/SrLaCuO point contacts at various temperatures and ma…
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…
Epitaxial MgB2 superconducting thin films with a transition temperature of 39 Kelvin
W. N. Kang, Hyeong-Jin Kim, Eun-Mi Choi +2
We report the growth of high-quality epitaxial MgB2 thin films on (1102) Al2O3 and (001) SrTiO3 substrates by using a pulsed laser deposition technique. The thin films grown on Al2…
Fluctuation Magnetoconductance in MgB2
W. N. Kang, Kijoon H. P. Kim, Hyeong-Jin Kim +8
We report fluctuation magnetoconductance in a MgB2 superconductor prepared under a high pressure of 3 GPa. This excess magnetoconductance, , follows the three-dimensional sc…
