The influence of substitution of Mn ions on quadrupole splitting of EuFeO3 perovskite oxide

Samples of EuFe_1-xMn_xO₃( =0.0–1.0) were prepared. XRD measurements show that a Jahn–Teller distortion occurs at =0.6. As increases, the Mössbauer spectra of the samples change from a simple six line spectrum for =0.0 to a doublet for 0.5 and QS increase from -0.02 mm/s to 1.05 mm/s for =0.8, which is caused by the decrease of the Curie temperature and by the Jahn–Teller distortion, respectively.
