Abstract
Resistivity (ρ), thermal conductivity (k) and Seebeck coefficient (S) of La1–xCexB6 single crystals with various concentrations of cerium Ce ions was measured in a wide temperature range 3−300 K. The obtained data were analyzed in the framework of the Coqblin–Shrieffer model. The contributions of scattering of carriers on magnetic ions Ce for all transport parameters ρ(T), k(T), S(T) are revealed. Strong dependence of the magnetic scattering on concentration of the cerium ions are identified. The anomalous behavior of the transport parameters ρ(T), k(T), S(T) in the region near 30 K is attributed to the Δ ~ 30 K splitting of Г8 level.
