HIGH RESIDUAL ELECTRICAL-RESISTIVITY OF CARBON-DOPED EUB6

Results Of electrical resistivity measurements of carbon doped EuB6 do wn to 50 mK are discussed. We have focused our attention on the high r esidual resistivity of this material below its magnetic transition tem perature. Additional measurements and the analysis of results have sho wn that the high residual resistivity at the lowest temperatures origi nates from the substantial amount of scattering of the conduction elec trons due to the presence of small ferromagnetic and helimagnetic doma ins in the sample.
