Description
57Fe Moessbauer study on the ordered double perovskite A2FeReO6 (A=Ca, Sr) has been conducted. Fe ions are in 2.5+ states that correspond to the hybridized state of 3d t2g down-spin electrons with Re5+ 5d t2g down-spin electrons. The orbital effect due to this seems to be absent. On the metal-insulator transition of Ca2FeReO6 specimen, slight change of the electronic state toward Fe3+ state is recognized. The quadrupole interaction is well explained by a point charge model, which may suggest that while the electrons of Re are itinerant, those of Fe stay rather localized. (author)
