Quasi one-dimensional hopping conductivity of the non-stoichiometric spin-ladder CaCu2O3 single crystals

Quasi one-dimensional hopping conductivity of the non-stoichiometric spin-ladder CaCu2O3 single crystals

Resistivity, ρ (T), of the spin-ladder compound CaCu2O3 is investigated between T ~ 100 − 350 K. Both nearest-neighbor hopping, ρ (T) ~ exp (Ea/kT), and variable-range hopping, ρ (T) ~ exp [(T0/T)3/4 ], quasi one-dimensional conductivity mechanisms are observed above and below T ~ 200 K, respe...
