Research Abstract

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.
