| 英文摘要 | Iron-nickel alloys such as kamacite, taenite and tetrataenite are the most important magnetic materials in chonclrites meteorites. In this study we studied the Jilin chondrite and found that kamacite containing 6%similar to 7% Ni has lower coercivity and a Curie temperature (T-c) of 750 degrees C; tetrataenite containing similar to 48% Ni has higher coercivity and a T-c of 565 degrees C. Signals of magnetization and magnetic susceptibility are carried by the former, but remanence is carried by the latter. Troilite (FeS) is antiferromagnetic at room-temperature and thus has no contribution to remanence, but it has a magnetic transition at similar to 60 K. Troihte is rather thermally stable as heating in argon, while it is oxidized and transformed to magnetite when heating in air. These results provide useful information in regard to magnetic properties of chondrite containing iron-nickel alloys. |
