Field-dependent heat transport in the Kondo insulator SmB6 : phonons scattered by magnetic impurities

M-E. Boulanger, F. Laliberté, M. Dion +12

The thermal conductivity $\kappa$ of the Kondo insulator SmB${}_6$ was measured at low temperature, down to 70 mK, in magnetic fields up to 15 T, on single crystals grown using both the f…
