Electronic and magnetic properties of composites were analyzed and their potential utilization in spintronics was discussed. Barriers of metal atoms migration from bigraphene surface to the interlayer space through the vacancy were estimated in order to consider both thermodynamic and kinetic aspects of composites experimental preparation. Formation of metal atoms inner-sorbed on bigraphene was found to demand harsh synthesis conditions; whereas outer-sorbed composites demonstrate significantly higher degree of spin polarization which makes them perspective for usage in spintronic devices. © 2015 Elsevier B.V.
