Temperature-dependent interplane resistivity ρc(T) was measured in an isovalent substituted iron-arsenide compound Ba(Fe1−xRux)2As2 over a substitution range from parent compound to slightly below optimal doping x=0.29. The feature of interest in the ρc(T), a broad resistivity crossover maximum found in the parent compound at Tmax≈200 K, shifts to higher temperatures with Ru substitution, ∼340 K for x=0.161 and goes out of the 400 K range for x=0.29. Nearly T-linear dependence of interplane resistivity is found at the highest substitution level x=0.29. This temperature-dependent ρc and its evolution with substitution bear close similarity to another type of isovalent substituted system BaFe2(As1−xPx)2. Similarly to the isovalent substitutions, the measurements of interplane resistivity in the parent BaFe2As2 compound under pressures up to 20 kbar also revealed a rapid rise in Tmax.
