Structural Realization of Oxygen Nonstoichiometry in Nickel-zinc Ferrite by Yu.D. Tretyakov; V.I. Fadeeva; V.K. Portnoi is a Materials Science article available to read on EtoBox.
We have carried out a study of nickel-zinc ferrite of composition Zno.21aNio.752Fe2.o304+y with varying oxygen nonstoichiometry 7. The method used was to measure the intensity of three groups of X-ray reflections on single crystal specimens with subsequent division of the amounts of mean-square dynamic and static displacement of the ions on the sublattices. From the amount of static displacement compared to two calculated models, one of which was based on an ionic approximation while the other was based on approximation of an elastically isotropic continuum, the character and distribution of point defects in the spinel structure was determined. It was established that in nickel-zinc ferrite with 7 0 vacancies appear in the octahedral cation sublattice.
