Erratum: Multiorbital Effects on the Transport and the Superconducting Fluctuations in LiFeAs [Phys. Rev. Lett. 109, 187005 (2012)]

Figure 1

(a) In plane resistivity versus temperature for the six samples of LiFeAs measured. An expanded view of the superconducting transitions is reported in the inset. Except for one sample, one can see a correlation between the values of $T_c$ and those of the residual resistivity. (b) Hall coefficient versus temperature for the three samples mounted in the van der Pauw configuration.

Figure 2

The transverse magnetoresistance measured in FP1 is plotted as a function of $H^2$ for $T>40\mathrm{K}$ in (a) and below 40 K in (b). At high $T$, the MR is linear in $H^2$ whatever $H$ while it recovers this variation only above a given threshold field $H_c^{\prime }$ (indicated by arrows) for $T\lesssim 50\mathrm{K}$. In the inset of (a), the MR coefficient $a(T)$ of Eq. (1) is plotted versus $T$ and $1/{\rho }^2$ for FP1 (empty red symbols) and FP2 (full blue symbols). The full lines of slope 1 indicate that Kohler’s rule is very well obeyed (see text). In the inset of (b) the resistivity measured in 14 T field down to 10 K is plotted versus $T^2$ for FP1, together with the extrapolated zero field data.

Figure 3

Superconducting fluctuation conductivity $\mathrm{\Delta }{\sigma }_{\text{SF}}$ for samples FP1 (red diamonds) and FP2 (black squares) as a function of $\epsilon =\ln (T/T_{c0})$, where $T_{c0}$ is taken at the midpoint of the transition. Estimates of the AL contribution in dimensions 2 and 3 are displayed as dashed lines for comparison.
