Díaz, J. Rodríguez-Núñez, A. Schmidt, I. Ţifrea] We studied the possible superconducting state in an electronic itinerant ferromagnetic system characterized by a density of states that presents a moderately strong peak that is controlled by a specific parameter a and is positioned near the band edge. Specifically, we investigated the superconducting critical temperature, T c , and the zero-temperature superconducting gap,Δ0. The analysis is done in a self-consistent way, the BCS mean-field equation being solved together with the electron density equation to trace possible changes in the system's chemical potential due to the strong correlations between the component electrons. We discussed the density dependence of the superconducting critical temperature and zero-temperature superconducting gap for various values of the control parameter a and of the electron-electron attractive interaction. In the zero temperature limit we derive the system's phase diagram and discuss the possible fermionic and bosonic regimes of the diagram as function of the strength of the attractive interaction.
