Paper Title:
DC and AC Electrical Properties of Sr2-xLixFeMnO6 Compound
  Abstract

The variations of dc conductivities (σ) of the Sr2-xLixFeMnO6 double perovskite system over a range of temperatures (100 ~ 300 K) and for several concentrations (0≤ x ≤ 0.4) of incorporated Li+ ions are well described by the equation σ = (B/T) exp(−Ea/kT) and show a decrease with decreasing temperature for a given doping. At a given temperature, σ tends to decrease with increasing x. The derived activation energy shows a gradual increase with x with a range of values that are lower than what is usually reported. The measured ac impedance is used to extract the relaxation frequencies as a function of composition and temperature.
