| 英文摘要 | We study the diamagnetism induced by thermal fluctuations above the superconducting transition of the iron pnictide ba(fe1-xnix)(2)as-2 with different doping levels. the measurements are performed with magnetic fields up to 7 t applied in the two main crystal directions. these data provide double information: first, they confirm at a quantitative level the applicability to these materials of a 3d-anisotropic ginzburg-landau approach valid in the finite field regime. then, they allow us to determine the doping-level dependence of the in-plane coherence length and of the superconducting anisotropy factor, gamma. our results provide a stringent confirmation of the large increase of gamma with the doping level, as recently proposed from magnetoresistivity measurements. the implications of the applicability of the model used to a multiband superconductor are discussed. |
