The authors present measurements of the critical temperature difference for the onset of thermal convection and the effective thermal conductivity in two [sup 3]He-superfluid-[sup 4]He mixtures. The mixtures were 6.8% and 9.8% by molar volume of[sup 3]He in [sup 4]He and the measurements were made f...
