Abstract

The electronic structure and magnetic properties of the high-temperature cubic phase of strontium ferrite SrFeO2.5 with the disordered location of oxygen vacancies have been calculated using the coherent potential method. The semiconductor character of the electronic spectrum of SrFeO2.5 is observed only at certain types of disordering of vacancies over the oxygen sublattice, which makes it possible to choose among structural models of the high-temperature phase proposed on the basis of experiments.
