Abstract:The crystal structure and magnetic properties of stoichiometric compounds Ln 0.7 Sr 0.3 Mn 0.85 Sb 0.15 O 3 , in which manganese ions are in a trivalent state, have been investigated. No coop erative orbital ordering has been found in the Ln = La composition, but structural parameters of the Ln = Nd composition indicate Jahn-Teller distortions. It has been shown that, as the ionic radius of lanthanide (Ln) decreases, structural distortions of the MnO 6 octahedron increase and the ferromagnetic component weaken… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
