FIG. 1 FIG. 1: (a), Temperature-dependent amplitude of the 330 T dHvA frequency in SmB6 (black circles) together with a fit (blue line) to AdHvA(T ) = AcRT,c + AfRT,f , in which RT,c = Xc/ sinhXc and RT,f = Xf/ sinhXf are the thermal damping factors, Xc = 2π 2m$^{∗}_{c}$kBT/$\hbar$eB andmore » Xf = 2π2m$^{∗}_{f}$kBT/$\hbar$eB, showing it to stem from the superposition of conduction electron-like and f -electron-like channels with effective masses m$^{∗}_{c}$ and m$^{∗}_{f}$ , respectively. The inset shows the same fit with a logarithmic T axis. (b) Collapsed curves of the low T region of the bulk conductance of SmB6 inferred from Fig. 2c, after subtracting the surface contribution σsurf from each curve, with a dotted line extending to T = 0 added as a guide to the eye. The inset shows similar collapsed curves from Fig. 2b.« less
