Abstract—

(Sm_1–xEr_x)₂Fe₁₇ (x = 0.1, 0.4) solid solutions have been prepared by induction melting and then hydrided to give high hydrogen content materials: Sm_1.8Er_0.2Fe₁₇H_4.4 and Sm_1.2Er_0.8Fe₁₇H_4.6. The main phase, 2 : 17, in the parent samples and products of hydrogenation has been shown to crystallize in the Th₂Zn₁₇ structure. The introduction of hydrogen into the crystal lattice of (Sm_1–xEr_x)₂Fe₁₇ (x = 0.1, 0.4) leads to an increase in both the unit-cell volume and Curie temperature. As a consequence, the saturation magnetization of the hydrides near room temperature is considerably higher than that of the parent compounds.

氢对（Sm 1–x Er x）2 Fe 17（x = 0.1，0.4）固溶体的结构和磁性的影响

摘要—

（Sm _{1- x} Er _x）₂ Fe ₁₇（x = 0.1，0.4）固溶体通过感应熔化制备，然后氢化得到高氢含量的材料：Sm _1.8 Er _0.2 Fe ₁₇ H _4.4和Sm _1.2 Er _0.8 Fe ₁₇ H _4.6。母体样品和氢化产物中的主相2:17已显示在Th ₂ Zn ₁₇结构中结晶。将氢引入（Sm _{1– x} Er _x）₂ Fe ₁₇（x = 0.1，0.4）导致晶胞体积和居里温度均升高。结果，氢化物在室温附近的饱和磁化强度显着高于母体化合物的饱和磁化强度。
