Intercalated Graphene

Dimension and symmetry reduction in magnetic structures, involving transition metal (TM) elements and their alloys, can induce higher spin moments and larger magnetic anisotropy with respect the 3D counterparts. 

Intercalation of 3d ferromagnetic metals/alloys beneath Gr is a viable route to optimize the Gr/3d ferromagnet state with enhanced spin and orbital moments. The strong ferromagnetic interface, with a homogeneous and smooth 3d metal/alloys layer, presents an out of plane easy magnetization axis, that switches by only increasing the number of layers of intercalated ferromagnetic alloy, preserving a strong ferromagnetic state.
