Abstract: Low-temperature transport has been studied in steady and pulsed magnetic field on a single crystal of SmB6. Measurements in the range of intrinsic conduction allowed us to determine the indirect gap E-g approximate to 20 meV and microscopic parameters of carriers. The results obtained in the region of extrinsic conduction are discussed within the Kikoin-Mishchenko polaron-exciton model of charge fluctuations with short-range excitonic states E-ex approximate to 3.5 meV, R-ex approximate to 6 Angstrom.
