项目摘要
Ferromagnetic carbon nano-particles can be prepared by the laser vaporization of a carbon powder in a hydrogen containing atmospheric pressure of Ar at high temperature. However, we cannot exclude a possibility of that such ferromagnetism is originated in the impurity iron containing in the carbon powder with the order 100 ppm. As a fact, it was found that the ferromagnetic feature disappeared when the impurity iron level lowered less than 10 ppm. On the other hand, we have succeeded to catch a very weak signal possibly based on the zig-zag edges formed in a highly nitrogen doped graphene film. This will be a clue for verifying the intrinsic carbon ferromagnetism.
铁磁碳纳米颗粒可以通过在含氢大气压Ar中高温激光蒸发碳粉末来制备。然而,我们不能排除这种铁磁性起源于碳粉中含有的100 ppm数量级的杂质铁的可能性。事实上,发现当杂质铁水平降低到小于10ppm时,铁磁性特征消失。另一方面,我们已经成功地捕捉到一个非常弱的信号,可能是基于在高度氮掺杂的石墨烯膜中形成的锯齿形边缘。这将是验证本征碳铁磁性的一个线索。
