Effect of size factor on the Ruddlesden-Popper single-slab compounds structure features
Character of influence of the strontium atoms replacement by smaller atoms of calcium on structure features of the Ruddlesden-Popper (Sr,Ca)LaScO4 (A2BO4) single-slab compoundis established. Structure of phase with a maximum degree of replacementhas determined by the Rietveld method. It is shown that such type of substitution increases a degree of AO9 interblock polyhedra deformation, mutual inclination of the BO6 octahedra and a decrease of A - О interblock bond. Presence of structure changes is the precondition for regulation of structural-dependent features of the materials on the base of scandates alkaline-earth and rare earth metals.
