Abstract

The influence of the oxygen content on the crystal chemical parameters of the LnBaCuFeO5 + δ (Ln = La, Pr) ferrocuprates is investigated using X-ray powder diffraction and IR spectroscopy. The electrical conductivity of these phases is studied. The chemical expansion coefficients αδ and the activation energies E a for electrical conduction are calculated. It is demonstrated that, for the LnBaCuFeO5 + δ (Ln = La, Pr) phases, the chemical expansion coefficients ad depend on both the ionic radius of Ln 3+ cations and the oxygen nonstoichiometry of the ferrocuprate, whereas the activation energies E a for electrical conduction are predominantly determined by the oxygen content in the samples.
