Coexistence of superconductivity and ferromagnetism in a gapped graphene-based system (FS) is theoretically investigated. The center-of-mass momentum, P, of a Cooper pair in FS is found to be P ∼ 2 Eex / fenced(ℏ vF sqrt(1 - (m / EFS)2)), where m, Eex, EFS are the rest mass energy of the Dirac elect...
