Abstract

Europium gadolinium ferrites (Eu1-xGdx)FeO3 (X=0, 0.2, 0.4, 0.6, 0.8) are synthesized. The results of the X-ray diffraction show that all the compounds possess a perovskite structure. Both the151Eu Mössbauer spectra and the57Fe Mössbauer spectra are measured. The151Eu Mössbauer spectra are considered to be the pure quadrupole spectra. The results show that the isomer shift and the quadrupole splitting of the151Eu spectra vary with x. The hyperfine filed of the57Fe Mössbauer spectrum depends on the unit-cell volume. The57Fe spectra of the samples synthesised by the high-pressure and high-temperature mothod show a part of paramagnetic structure.
