Abstract

The mechanism and energy parameters of cooperative interactions between point defects, vacancies, and interstitial ions, in the lattice of LaF3-type superionic trifluorides are studied. The mean energy of interaction between two pairs of the defects is determined (λ = 0.032 eV) in the dipole approximation. It is shown that cooperative interactions in the “quasi-liquid” lattice of LaF3 decrease the defect formation energy down to values on the order of ≈kT.
