Experimental results showing the temperature dependence of the conductivity of a variety of PrREBaCuO (RE = Er, Yb, Lu, and Tm) compounds are presented. The semiconducting behavior of the conductivity observed is analysed using In σ ∼ T −2/5 and In σ ∼ T −1/4 laws suggested, using the small‐polaron hopping model by Triberis et al., for the high‐ and low‐temperature regime, respectively. The agreement of the experimental data with these models is very satisfactory, giving a meaningful interpretation of the transport mechanism of these materials.
