Their rhombohedral perovskite structure is confirmed by XRD patterns and exact chemical composition is determined by XRF (X-ray fluorescence) spectroscopy. The mean size of the as-prepared crystallites is of about 50 nm, the grains are rather separated and do not form sintering bridges that were typical for products synthesized by sol-gel routes followed by annealing. On the other hand, the synthesized nanoparticles exhibit rather low magnetization and decreased Curie temperature. Their neutron diffraction study indicates a complex magnetic ordering together with anomalously high atomic displacements factors that decreased considerably after annealing the samples at elevated temperature.
