The rare-earth–iron intermetallic compounds SmTiFex, with x ranging between 8 and 10, have been synthesized by an arc-melting technique. We found that they crystallize in the ThMn12-type tetragonal structure, I4/mmm. Unusual uniaxial magnetocrystalline anisotropies have been observed. The c axis is the easy magnetization direction. Curie temperature is 610 K. After the discovery of the R2Fe14B compounds, we have other ternary rare-earth–iron intermetallic compounds with strong uniaxial anisotropy.
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.
