Electronic and Magnetic Structures of Sr2FeMoO6

摘要: We have investigated the electronic and magnetic structures of Sr2FeMoO6 employing site-specific direct probes, namely x-ray absorption spectroscopy with linearly circularly polarized photons. In contrast to some previous suggestions, results clearly establish that Fe is in formal trivalent state this compound. With help light, it unambiguously shown moment at Mo sites below limit detection (<0.25 µB), resolving a controversy. also show decrease observed magnetization measurements from theoretically expected value driven by presence mis-site disorder between sites.
