Peculiar behavior of V on the Curie temperature and anisotropy field of SmFe12-xVx compounds

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

“…[1][2][3][4][5] The bulk phase of SmFe 12 is attempted to be stabilized by partial substitutions of nonmagnetic elements for Fe. [6][7][8][9][10][11][12][13] On the other hand, to improve the performance of permanent magnets, it is necessary to design microstructures with nonmagnetic grain-boundary subphases. 5,[13][14][15][16][17][18] In fact, however, ferromagnetic bcc Fe often precipitates by substituting nonmagnetic elements for some of Fe atoms in SmFe 12 .…”
