a The MR = 100*[ρ(B, T) − ρ(B = 0, T)]/ρ(B = 0, T) exhibits a crossover with temperature from positive to negative values around T = 12.8 K. b At this temperature, the thermal conductivity is greatly suppressed with increasing magnetic field. The inset shows comparison of maximum change in thermal conductivity and electrical resistivity. The dashed line demarcates T = 12 K which is the point at which the difference with and without magnetic field in the thermal conductivity is maximal and that in the resistivity is minimal. Legend is shared with panel d, c. Low temperature dilation measurements. d The MR plotted as a function of applied magnetic field demonstrates the close-to-zero value at T = 12.8 K.
