NMR spectra of ⁵⁷Fe dispersed europium orthoferrite in powder samples with micro- and nanocrystalline particles were studied for the first time. The material was synthesized by glycine–nitrate combustion, which allowed to obtain the specimens with granular diameters of 60 nm (nano-EuFeO ₃) and 1.5μm (micro-EuFeO ₃). It was found out that the spectra are more complex than could be expected for a compound with a single crystallographic position of Fe ^{3 +} ions, and it was also identified that there is a noticeable difference in samples with different fineness. Assumptions about the possible physical nature of the observed effects are made.
