| heal.abstract | Polycrystalline double perovskites Sr2Fe1-xCr xMo1-xWxO6 with x = 0, 0.05, 0.10, 0.15, 0.20, and 0.30 have been prepared by sold state reactions. A continuous decrease of the tetragonal unit cell parameters α and c with increasing x values is observed. The highest Curie temperature T C = 426 K is recorded for the x = 0.10 compound. 57Fe M?ssbauer spectroscopy measurements indicate a non-integral electronic configuration of ?3d 5.3 for the Fe ions at the ordered double perovskite structure for x ?0.20, which reaches ?3d5.4 for x = 0.30. Fe-Mo/W anti-site and anti-phase boundary defects are observed in all samples in equal concentrations of around 3% of the total number of Fe ions in their structure. © 2006 Springer Science+Business Media, Inc. | en |
