Abstract

The temperature dependence of the magnetic component of the activation energy of hopping conductivity ɛm of manganites in the paramagnetic phase (ɛm = ɛ 0m ± a/T, where the signs “+” and “−” correspond to the antiferromagnetic CaMnO3 − δ and ferromagnetic La0.85Sr0.15MnO3 manganites, respectively) has been found and investigated. The results obtained have been qualitatively explained on the basis of the model proposed by Gor’kov and colleagues.
