| 中文摘要 | Bulk superconductivity was observed in the FeAs-based RE1-xSrxFeAsO (RE = La, Pr) when the di-valence element Sr was Substituted to the site of the tri-valence element La and fir. The maximum superconducting transition temperatures T, for the two systems are 26 K and 16.3 K, respectively. The doping dependence of the electrical properties and structure of these two systems were investigated systematically. A roughly monotonic increase of T-c and the lattice constants (a-axis and c-axis) with Sr concentration and a saturation behavior in the high doping levels were found. We confirmed that conduction in this type of materials is dominated by hole-like charge carriers by the Hall effect measurements. Also the resistive measurements revealed possible higher upper critical field in these systems comparing with the electron-doped ones. (C) 2009 Elsevier B.V. All rights reserved. |
