摘要：

The Fe(IV) disproportionation (2Fe(IV) reversible Fe(III) + Fe(V) was.studied through Mossbauer spectroscopy using 119Sn(IV) as diamagnetic probe at the Fe(IV) site. The spectrum observed at 4.2 K was treated by the Hesse and Rabartsch's method. The magnetic fields distribution underlines the presence of two field-values : (i) one preponderent close to 20 kOe is attributed to six Fe(V) as first neighbours and the other near 90 kOe corresponding to a surrounding of five Fe(V) and one Fe(III). Such distributions, different than that observed for Sn(IV), as probe into SrFeO3, could be induced by predominant steric effects into the CaFeO3 lattice.
