Outline of Final Research Achievements |
We investigated magnetism of cementite and tried controlling the precipitation of cementite from pure iron under magnetic field. As a result, we found that the easy axis is c axis of orthorhombic structure, the 2nd easy axis is b axis and a axis is hard axis. We also estimated the magnetocrystalline anisotropy energy at the temperature between 5 K and 350 K. Using these results, we tried controlling the precipitation of cementite from pure iron under magnetic field and found that the more variants of cementite which has low magnetocrystalline anisotropy energy precipitate than the other of 12 variants in BCC iron single crystal.
