Normalized residual linear term κ₀/T of ZrTe_2.956Se_0.044 and ZrTe_2.949Se_0.051 single crystals as a function of H/H_c2. Similar data of the clean s-wave superconductor Nb,^[23] an overdoped d-wave cuprate superconductor Tl-2201,^[21] and the multiband s-wave superconductor NbSe₂^[24] are also plotted for comparison.
