The structural and magnetic properties of (Sm, Y)(Fe0.8Co0.2)12−xTix (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 (Sm0.8Y0.2)(Fe0.8Co0.2)11.4Ti0.6. 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 (Sm0.8Y0.2)(Fe0.8Co0.2)11.4Ti0.6 exhibited μ0Ms = 1.50 T, μ0Ha = 11 T, and Tc = 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。
