“…The maximum of uniaxial anisotropy in Y(Fe 1−x Co x ) 11 TiH is obtained at x=0.1 while experiments found the maximum at YFe 9 Co 2 TiH. [60] For the Fe-rich CeCo 11 TiZ, only H doping slightly increases the MAE, while C and N quickly decrease uniaxial anisotropy. For Y(Fe 1−x Co x ) 11 TiZ, it is unlikely we can have better uniaxial anisotropy (at least at low temperature) over the whole range of Co composition.…”

“…A similar feature had been observed experimentally. [60] It is caused by the partial occupation of Co on 8f sites in YFe 11 Ti. We found that replacing Fe atoms in YFe 11 Ti with Co atoms on the 8f sites increases the MAE.…”

“…For example, upon hydrogenation, a significant increase of K 1 with a factor 1.8 was observed in YFe 9 Co 2 Ti at room temperature. [60] To our knowledge, simultaneous doping of Co and interstitial elements C and N atoms is not well studied. We calculated the MAE dependence on Co compositions in Ce(Fe 1−x Co x ) 11 TiZ with Z=H, C, and N, and results are shown in Fig.…”
