The Influence of Diamagnetic Ions to Features of Crystalline and Magnetic Structures of BaFe11.9M0.1O19($\text{M}= \text{In}$ and Sc)

Abstract

The features of crystalline and magnetic structure of solid solution of barium ferrite BaFe11.9M0.1O19 (where M= In and Sc) with neutron diffraction method was studied. The substitution of Fe by In ions leads to increase of volume of unit cell while replacing with Sc ions insignificantly change the lattice parameters. The behavior of magnetic structure and unit cell parameters and atomic coordinates has been refined in a broad range of ambient temperature. The refinement of the magnetic structure was carried out within the framework of Gorter's model. The microstructural parameters of solid solutions BaFe12-xMxO19 (M= In and Sc) were determined by the high-resolution neutron diffraction method.
