The structural and magnetic properties of (Sm, Y)(Fe0.8 Co0.2 )12−x Tix (x = 0.6, 1) prepared by arc melting are investigated. The formation of the ThMn12 structure was facilitated by the substitution of Sm with Y at low Ti concentrations (x = 0.6), and almost a single phase with the ThMn12 structure was obtained for (Sm0.8 Y0.2 )(Fe0.8 Co0.2 )11.4 Ti0.6 . This suggests that Y plays an important role in stabilizing the ThMn12 structure owing to the decrease in the atomic radius of the rare earth site. The intrinsic magnetic properties of (Sm0.8 Y0.2 )(Fe0.8 Co0.2 )11.4 Ti0.6 exhibited μ 0 M s = 1.50 T, μ 0 H a = 11 T, and T c = 820 K at room temperature.

Y取代对Sm(Fe0.8Co0.2)11.4Ti0.6结构和磁性能的影响
研究了电弧熔炼制备的(Sm, Y)(Fe0.8Co0.2)12−xTix (x = 0.6, 1)的结构和磁性能。在低Ti浓度(x = 0.6)下,用Y取代Sm有利于ThMn12结构的形成,并且(Sm0.8Y0.2)(Fe0.8Co0.2)几乎获得了具有ThMn12结构的单相)11.4Ti0.6。这表明,由于稀土位点原子半径的减小,Y 在稳定 ThMn12 结构方面发挥着重要作用。 (Sm0.8Y0.2)(Fe0.8Co0.2)11.4Ti0.6的本征磁性能在室温下表现出μ0Ms = 1.50 T、μ0Ha = 11 T和Tc = 820 K。
