Abstract
The infrared conductivity σ(ω) of very-high-resistivity ruthenates
and cuprates (in the normal state) was recently found to deviate from
the usual Drude behavior - σDrude(ω) ∝ ω−2. We have included the
Pippard ineffectiveness condition in the analysis of σ(ω), and obtained
that for very-high-resistivity materials, σ(ω) ∝ ω−α, with α ¿ 2.
Therefore, the Pippard condition might be a partial explanation for
the non-Drude behavior observed for the infrared conductivity of the
ruthenates and cuprates.
