Abstract A series of (Nd1-xSmx)Fe11Ti alloys with the ThMn12 crystal structure have been fabricated and characterized in order to promote a strong uniaxial anisotropy in NdFe11Ti without the need of nitrogenation. The compounds show small changes in the lattice parameters and cell volume, as well as Curie temperature and spontaneous magnetization. The anisotropy field, however, rapidly increases with the incorporation of Sm and overcomes the effect of nitrogenation, reaching values > 4 T for a 30% Sm content. Mossbauer spectroscopy indicates that the quadrupole splitting is correlated with the magnetic anisotropy. These alloys are good candidates for permanent magnets, provided the correct microstructure is developed to increase coercivity.

(Nd1-xSmx)Fe11Ti的本征磁特性

摘要 一系列具有 ThMn12 晶体结构的 (Nd1-xSmx)Fe11Ti 合金已被制造和表征，以促进 NdFe11Ti 的强单轴各向异性，而无需氮化。这些化合物的晶格参数和晶胞体积以及居里温度和自发磁化强度变化很小。然而，各向异性场随着 Sm 的掺入而迅速增加并克服了氮化的影响，当 Sm 含量为 30% 时，其值达到 > 4 T。穆斯堡尔谱表明四极分裂与磁各向异性相关。如果开发了正确的微观结构以增加矫顽力，这些合金是永磁体的良好候选者。
