中文摘要 | The structural details of the Pr1-xSrxFeAsO (1111) superconducting system are analyzed using data obtained from synchrotron x-ray diffraction and the structural parameters are carefully studied as the system moves from non-superconducting to hole-doped superconducting with an increase of the Sr concentration. Superconductivity emerges when the Sr doping amount reaches 0.221. The linear increase of the lattice constants proves that Sr is successfully introduced into the system, and the Sr concentration can be accurately determined by electron density analyses. The evolution of structural parameters with Sr concentration in Pr1-xSrxFeAsO and comparison of them to other similar structural parameters of the related Fe-based superconductors suggest that the interlayer space between the conducting As-Fe-As layer and the insulating Pr-O-Pr layer is important for improving T-c in hole-doped (1111) superconductors, which seems to be a different trend from that encountered in the electron-doped systems. |
