摘      要：The chemical formula for rare earth-ferro nitrides is RxFeyNz,where R represents a rare earth *** rare earth-ferro nitrides include two types of materials with different chemical compositions and crystal structures:(1) Nd(Fe,M)12Nx or Pr(Fe,M)12Nx,where M=Ti,V,Mo,etc.,having a ThMn12-type tetragonal crystal structure,commonly referred to as Neodymium-FerroNitrogen (NdFeN);(2) Sm2Fe17Nx, having a Th2Zn17-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.
