Abstract
Eu1−xSrxFeO3 (x=0, 1/4, 1/3, 1/2, 2/3 and 1) perovskites were prepared using conventional solid-state method. Structure aspects of the Eu1−xSrxFeO3 were studied by powder X-ray diffraction. The results showed that Eu1−xSrxFeO3 (x=0, 2/3) was single phase with orthorhombically distorted structure. For samples with x=1/4, 1/3 and 1/2, phase segregation was observed. The Mössbauer spectra showed that Fe4+ appeared as the Eu3+ was replaced by Sr2+, EuFeO3-like phase existed in systems with x=1/4, 1/3 and 1/2. The corresponding oxygen vacancies were also calculated from the Mössbauer spectra.
