Thermal fluctuation conductivity and dimensionality in iron-based superconductors

Wang Rui^{1, 2, †,}, Li Ding-Ping^{1, 2, ‡,}

The superconducting fluctuation electrical conductivities of (a) the F-doped compound LaOFeAs and (b) the single crystal BaFe_2−xNi_xAs₂. The lines are given by the theoretical fitting formula Eq. (26) of conductivity under different magnetic fields. The points are taken from the experimental data.
