Abstract

Double perovskite Sr2FeMoO6 with cation disorder was investigated by means of the X-ray diffractometry, atomic resolution transmission electron microscopy, AC susceptibility, and 57Fe Mössbauer spectroscopy. Atomic resolution TEM measurements revealed the existence of domains with modulated crystal structure inside regions of the ideal double perovskite. 57Fe Mössbauer spectroscopy revealed that cation disorder leads to a suppression of delocalization of the 4d 1 electron of Mo5+, and consequently regions with cation disorder form insulating domains in the half-metallic matrix of the ordered double perovskite structure.
