摘要
A physically justified equivalent circuit of an ionic-electronic conductor has been proposed which accounts for the unusual electrical behavior of BiMg0.25Cu0.75NbO5. The problem of separating the electronic and ionic contributions to its conductance has been resolved by analyzing the frequency dependences of its impedance. A new approach has been proposed for interpreting the temperature dependences of capacitance and conductance for this material.
