通过在（Mn，Fe）（2）（P，Si）中掺杂B，C和N原子，可以调节（Mn，Fe）（2）（P，Si）的临界温度和磁弹性转变的一阶特性。中子衍射实验表明，B取代了六方P-62 m结构的lb位Si，C占据了间隙位6 j和6 k，而N则分布在lb位和间隙位6 j和6 k上。调谐机制已被讨论的Fe原子周围的电子配置的微妙变化，这可以用来定制的磁弹性转变。(C)2016爱思唯尔有限公司版权所有
The critical temperature and first-order character of the magnetoelastic transition in (Mn,Fe)(2)(P,Si) are tunable by doping the structure with B, C and N atoms. Neutron diffraction experiments reveal that B substitutes Si on the lb site of the hexagonal P-62m structure, C occupies the interstitial 6j and 6k sites, while N distributes on both the lb and interstitial 6j and 6k sites. The tuning mechanism has been discussed in terms of the subtle variations in electronic configuration around the Fe atoms, which can be used to tailor the magnetoelastic transition.
