Abstract This research focuses on the theoretical investigation of the possible coexistence of superconductivity and ferromagnetism in Ce doped SrFBiS Superconducting. By developing a model Hamiltonian for the given system and by using the double time temperature dependent Green‟s function formalism, we obtained expressions for superconducting transition temperature (Tc), magnetic ordering temperature (Tm), superconducting and magnetic ordering parameters (  ) and ( 2  ) respectively. By using the experimental and theoretical values and by considering some plausible approximations of the parameters in the obtained expressions, the phase diagram of superconducting transition temperature versus magnetic ordering parameter and magnetic ordering temperature, versus magnetic ordering parameter are plotted. Finally, by combining the two phase diagrams, we showed the possible coexistence of superconductivity and ferromagnetism in Ce doped SrFBiS 2 Superconductor Key words: Superconductivity, Ferromagnetism, Order parameter, Green‟s function, Ce doped S r FBiS 2
