Abstract
Solid solutions of the nominal composition La1–y□yMn1–xFexO3±δ (y = 0, 0.1, 0.2, x = 0.5, 0.55, 0.58) with the non-stoichiometric concentration of La cations are synthesized by the polymer-salt composition method and characterized by a set of physicochemical techniques. An increase in the degree of Fe cation doping is shown to decrease the particle size of solid solutions with retaining the perovskite structure. Particle enrichment with Fe cations and the presence of disordered crystal structure layers on the perovskite phase surface is detected by high-resolution transmission electron microscopy. According to the thermogravimetric data, the composition with x = 0.58 is characterized by a smaller weight loss, which seems to be due to the partial blocking of the perovskite phase surface by disordered layers enriched with Fe.
期刊介绍：
Journal is an interdisciplinary publication covering all aspects of structural chemistry, including the theory of molecular structure and chemical bond; the use of physical methods to study the electronic and spatial structure of chemical species; structural features of liquids, solutions, surfaces, supramolecular systems, nano- and solid materials; and the crystal structure of solids.
