Structure Analysis of Sm2(Fe,Mn)17Nz Magnet

摘要：

In order to understand the coercivity mechanism of Sm2(Fe,Mn)17Nx magnet, the structure of amorphous phase found in the crystal phase was clarified using a TEM-tomography. It was found that amorphous phases precipitated as a fine wire in the crystal phase that differs with the phase separation in Sm-Co magnets. It may say that different coercivity mechanism should be proposed in each Sm2(Fe,Mn)17Nx and Sm-Co magnets.
