Electrical and thermal transport properties of Cr-Si alloy single crystals

Electrical resistivity (ρ), Seebeck coefficient (S) and thermal conductivity (κ) measurements on Cr1-xSix alloy single crystals with x = 0.005, 0.012 and 0.016 reveal novel features not previously detected in polycrystalline alloys. Our results prove thermal transport to be an experimental probe that is especially well disposed towards exposing spin-density-wave ordering in an itinerant system such as Cr-Si.
