Abstract
The study of conductivity in combination with Hall and Seebeck coefficients has been carried out along different crystallographic directions in the classic mixed-valence compound at helium and intermediate temperatures. The experiments on high-quality single crystals of samarium hexaboride have revealed a strong anisotropy of the low temperature transport parameters. The “induced anisotropy” in this cubic material may be explained in terms of exciton-polaron complexes formed at and an onset of a coherent state or condensation of these quasiparticles at
