Abstract:
We have studied the magnetic and electronic properties of double perovskites A2 FeReO6 with A = Ba and Ca using ab initio methods based on density functional theory. It has been shown that when changing Ba by Ca the system undergoes a metal-insulator transition coincidentally to a structural phase transition, even if conduction band fillings are not significantly changed. Our results suggest that only considering a quite large correlation term on the Re site could explain an insulating character for Ca2 FeReO6. Instead, we found that small correlations could induce a bad metallic behavior as suggested in more recent experiments. © 2009 Elsevier B.V. All rights reserved.
