One-dimensional hopping conductivity of the spin-ladder CaCu2O3 single crystals

Resistivity, ρ, of the spin-ladder compound CaCu2O3 is investigated between T ~ 130− 450 K. The ρ (T) data exhibit an activated dependence characterized by a nearest-neighbor hopping followed by a variable-range hopping (VRH) regime when T is decreased. The observed VRH conductivity on the low-te...
