摘要：

SmFe12-based compounds with the ThMn12-type structure have a great potential as future rare-earth-lean permanent magnets. However, their reliance on stabilizing non-magnetic elements has impeded practical applications. Therefore, elements such as Gd, Y, and Zr have gained popularity as candidates to minimize the need for stabilizing elements by reducing the formation energy of the ThMn12 (1:12) phase. This study examines the effect of Gd, Y, and Zr on the intrinsic and hard magnetic properties in (Sm1-xRx)1.2Fe8.4Co2.1V1.5 (or with nominal composition of (Sm1-xRx)9.1Fe63.6Co15.9V11.4) with a single 1:12 phase for 0 <= x <= 0.3. Notably, samples substituted with Gd exhibit an enhanced temperature dependence of the magnetic properties.
