Popis:	A neutron-diffraction study was performed on micro- and nanocrystalline BaFe10.3Co0.85Ti0.85O19 samples prepared by soft chemistry. Substitution and grain-size effects on the crystal structure were analysed in the P63/mmc space group using Rietveld refinement. It was established that the (Co2+, Ti4+) substitution causes significant distortions in the local oxygens surrounding ferric cation sites, while the grain-size effect on the structural parameters is considerably smaller.
