In-plane \(\kappa /T\) of the \(\hbox {2H-Pd}_{0.08} \hbox {TaSe}_2\) single crystal at various magnetic fields applied along the c-axis. The red dotted lines are the fitting curves of \(\kappa /T = \kappa _0/T + aT^{n-1}\) with \(n = 2\) to the data at \(\mu _0H\) = 0 T and 2.5 T below 200 mK. As the magnetic field reaches 2.5 T, which is comparable to \(\mu _0H_{c2}^c (0) = 2.45 \text { T}\), \(\kappa _0/T\) reaches to the value expected from the Wiedemann–Franz law at the normal state, \(\kappa _N/T = L_0/\rho _N\) = 163 \(\upmu \)W/\(\hbox {K}^{2}\) cm (blue dashed line). The magnetic field dependence of extracted \(\kappa _0/T\) is summarized in Fig. 6.
