结构为CaZn_5型的钐钴合金具有高的磁特性。在文献中用接近化学计量成分的合金SmCo_5(33.8％Sm)得到如下的性能:(BH)_(max)=18.5×10~6高·奥、Br=8700高斯、B_H_C=8400奥斯特、I_H_C=15800奥斯特。文献建立了Sm-Co合金系的状态图。根据这个相图,化合物SmCo_5在高温时具有一个从66.2到70％Co的可溶区。钐在化合物SmCo_5中的溶解度不大。这些作者在文献中报道,增加钴含量(同该元素在
Samarium-cobalt alloy with CaZn_5 structure has high magnetic properties. The following properties were obtained in the literature with an alloy SmCo_5 (33.8% Sm) close to the stoichiometric composition: (BH) _ (max) = 18.5 × 10 -6 high · A, Br = 8700 Gauss, B_H_C = 8400 Oersted, I_H_C = 15800 Ost. Literature established the state diagram of the Sm-Co alloy system. According to this phase diagram, the compound SmCo_5 has a soluble region from 66.2 to 70% Co at elevated temperatures. The solubility of Sm in the compound SmCo_5 is not large. These authors reported in the literature that increasing the cobalt content (with the element in the
