Abstract:BaFe 12−2x M x Sn x O 19 compounds, where M=Sn 2+ , Ni 2+ or Zn 2+ ions, were synthesized by mechanical milling and partially by citrate precursor methods. Analysis of magneto-crystalline structure has been carried out by Mössbauer spectroscopy. The Sn 4+ ions replace Fe 3+ ions on 2b and slightly on 2a+4f 1 sites, Zn 2+ ions strongly prefer 4f 1 sites, Sn 2+ ions prefer 4f 1 sites too and Ni 2+ ions occupy 4f 2 and 12k or 2a sites. The magnetic properties were evaluated by the vibrating sample magnetometry an… 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.
