In the first part of the talk we will report first-principles investigation of the electronic and magnetic properties of adatom on bilayer graphene. In particular, we studied the influence of an applied gate-voltage.[1,2] In the second part, we will discuss the manipulation of magnetism in small sized hexagonal graphene nanoflakes.[3,4] The effect of carrier doping, chemical modification at the edge, and finite temperature on the edge magnetism has been studied.
