Étude par effet Mössbauer du fluoronitrure de fer Fe4N3F3
Résumé
The 57Fe Moessbauer spectrum of Fe4N3F3 was paramagnetic from room temperature to 113°K with a chem. shift (0.384 mm/sec) and quadrupole splitting (0.745 mm/sec) characteristic of high-spin Fe3+ and indicative of marked covalent character of the Fe-N bond. At 4.2.degree.K, the spectrum is composed of 2 Zeeman structures corresponding to 2 crystallog. sites occupied by Fe atoms in a bixbyite-type structure.
