Figure 6
Field dependence of the residual linear term \(\kappa _0(H)/T\) of the \(\hbox {2H-Pd}_{0.08} \hbox {TaSe}_2\) single crystal. The \(\kappa _0(H)/T\) is normalized by the normal-state residual linear term \(\kappa _N/T\) = 163 \(\upmu \)W/\(\hbox {K}^{2}\) cm and H is normalized by \(\mu _0H_{c2}^c(0)\) = 2.45 T. The \(\kappa _N/T\) is estimated by the Wiedemann–Franz law and the \(\mu _0H_{c2}^c(0)\) is determined from the resistivity measurements (see the text). Error bars correspond to uncertainty in the extrapolation from the power-law fitting. For comparison, \([\kappa _0(H)/T]/[\kappa _N/T]\) of a d-wave superconductor \(\hbox {Tl}_2 \hbox {Ba}_2 \hbox {CuO}_{6+\delta }\) (Tl-2201)54, a multigap nodeless superconductor \(\hbox {2H-NbSe}_2\)17, a dirty nodeless superconductor InBi50, and a single nodeless superconductor Nb46 are plotted together.
