Abstract

We propose an explanation for the temperature dependence of the resistivity of Cd $_{2}$ Re $_{2}$ O $_{7}$ , including the regime above the structural phase transition at $T$ =200 $^{o}$ K. The mechanism involved relies on the existence of a strong van Hove singularity close to the Fermi surface, which is evidenced by relevant band structure calculations. The same mechanism has successfully described the $T$ -linear resistivity of the cuprates and Sr $_{2}$ RuO $_{4}$ , and the one-particle scattering rate in the former materials, as corroborated by recent experiments. We describe a few predictions for Cd $_{2}$ Re $_{2}$ O $_{7}$ and Cd $_{2}$ Os $_{2}$ O $_{7}$ .
