Samples of the compound EuFeO3: ∑AC/∑Mn+ = 0.8; 0.9; 1.1; 1.3; 1.5 with orthorhombic structure were fabricated by gel – citrate method. The Survey of X-ray diffraction has showed that all samples are the single-phase with standard orthorhombic structure of EuFeO3 and belong to the Pnma space group. The average particle size of the EuFeO3 powder is about 16 nm; lattice parameters increase as the citric acid concentration increases.The expected molecular structure and the mixture of valence Fe3+/Fe2+ of EuFeO3 are showed through the FTIR results.
