摘　　要：The chemical formula for rare earth-ferro nitrides is R_(x)Fe_(y)N_(z),where R represents a rare earth element.Anisotropic rare earth-ferro nitrides include two types of materials with different chemical compositions and crystal structures:(1) Nd(Fe,M)_(12)N_(x) or Pr(Fe,M)_(12)N_(x),where M=Ti,V,Mo,etc.,having a ThMn_(12)-type tetragonal crystal structure,commonly referred to as Neodymium-Ferro-Nitrogen (NdFeN);(2) Sm_(2)Fe_(17)N_(x), having a Th_(2)Zn_(17)-type rhombohedral crystal structure,abbreviated as Samarium-Ferro-Nitrogen (SmFeN).The academic community refers to these two types of materials collectively as rare earth-ferro nitrides.
