Crystal and magnetic structures of new layered perovskites of possible oxygen storage compounds LaBaFeMnO5 and LaBaFeMnO6

DOI

New layered perovskite compounds LaBaFeMnO5 and LaBaFeMnO6 were recently synthesized. They may be useful for future oxygen storage applications. Fe-Mössbauer spectroscopy has revealed that Fe3+ spins in LaBaFeMnO5 are antiferromagnetically ordered at 300 K while spin ordering for LaBaFeMnO6 is below room temperature. Precise determination of Fe-Mn ordering at the B sites, taking advantage of the high scattering contrast (b(Fe/Mn) = 9.5/-3.7 fm), and oxygen occupancy are crucial for the study of present materials. It is also very important to determine the detailed magnetic structures to understand the physical properties. We request 3 days on WISH to follow the temperature evolution of the crystal structure and magnetic order in the new LaBaFeMnO5 and LaBaFeMnO6 compounds.
