(Sm,Zr)Fe${}_{12-x}$M${}_x$ (M=Zr,Ti,Co) for permanent-magnet applications: Ab initio material design integrated with experimental characterization

Munehisa Matsumoto, Takafumi Hawai, Kanta Ono

In rare-earth permanent magnets (REPM's), trade-off's between intrinsic magnetic properties are often encountered. A recent example is SmFe${}_{12}$ where excellent magnetic properti…
