Název v původním jazyce

Transport and magnetic properties of Mo2.5Ru0.5Sb7-xTex.

Popis výsledku v původním jazyce

Transport properties including electrical resistivity, thermopower, and thermal conductivity of polycrystalline Mo2.5Ru0.5Sb7-xTex compounds for 0 x 1 have been investigated in the 2?1000 K temperature range.Additional information on the concentrations and the scattering mechanisms of the charge carriers as well as on the magnetic properties has been obtained through Hall effect and magnetic susceptibility measurements performed in the 5?300 K temperature range. The enhancement in the Te content resultsin a decrease in the carrier concentration which is at the origin of the simultaneous increase in the electrical resistivity and thermopower. A single parabolic band model with acoustic phonon scattering enables to explain the compositional and temperature dependence of the thermopower while such a simple model fails to adequately describe the electronic thermal conductivity.
