Heatmap from Scientific Research

The normalized excess thermal conductivity ( H )/ (11.9 T) = [ ( T , H ) ( T, 11.9 T)]/ ( T, 11.9 T) plotted as a colour map on the magnetic field H and the temperature T plane. The excess conductivity ( H )= ( H ) (11.9 T) is the deviation from ( T ) at 11.9 T. (11.9 T) data can be regarded as a phonon-only contribution to in the absence of scattering by magnetic excitations.
