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 Psimilarity2Eex/similarityvF1-(m/EFS)2, where m, Eex, EFS are the rest mass energy of the Dirac electron, ex...
