Phase equilibria of Sm-Fe-Ti-M (M = Cu, Ag) systems and wetting behavior of M-Sm alloys on SmFe11Ti substrate

Structures of Sm–Cu intermetallics with Fe as subphase candidates in SmFe12-based permanent magnets studied by first-principles thermodynamics

“…Recently, it has been reported experimentally that a Cu-41 at%Sm alloy equilibrates with SmFe 11 Ti. 20) Stoichiometric SmCu has been examined as a prototype subphase for SmFe 12 -based magnets by first-principles calculations, where the most stable B27 structure was used for SmCu intermetallics. 21) Binary SmCu intermetallics have two possible crystal structures: the B2 structure (CsCl type, Pm m 3 ) and the B27 structure (FeB-b type, Pnma).…”
