Research output: Contribution to journalArticlepeer-review


Europium gadolinium ferrites Eu1-xGdxFeO3 (x=0, 0.2, 0.4, 0.6 and 0.8) were synthesized under constant pressure, high temperature and high pressure, high temperature respectively. A Rigaku X ray diffractometer with copper rotating target was used to analyse the structures of these compounds, and the results show that all compounds possess a perovskite structure. Both the 151Eu and 57Fe Mossbauer spectra were measured using OXFORD MS-500 Mossbauer spectrometer. For 151Eu the pure quadrupole spectra are obtained, meanwhile both ismer shift and quadrupole splitting vary with x. The hyperfine field of the 57Fe Mossbauer spectrum depends linearly on the unit-cell volume. The 57Fe spectra of the samples synthesized under high temperature and high pressure, show a partial paramagnetic structure.
