Observation of ferromagnetic semiconductor behavior in manganese-oxide doped graphene

Autor: Chang-Soo Park, Yu Zhao, Yoon Shon, Chong S. Yoon, Haigun Lee, Cheol Jin Lee

Publikováno v: AIP Advances, Vol 4, Iss 8, Pp 087120-087120-7 (2014)

We have doped manganese-oxide onto graphene by an electrochemical method. Graphene showed a clear ferromagnetic semiconductor behavior after doping of manganese-oxide. The manganese-oxide doped graphene has a coercive field (Hc) of 232 Oe at 10 K, an
