Abstract: We developed the self-consistent method for the calculation of the density of states $N(\varepsilon)$ in the SF bilayers. It based on the quasi-classical Usadel equations and takes into account the suppression of superconductivity in the S layer due to the proximity effect with the F metal, as well as existing mechanisms of the spin dependent electron scattering. We demonstrate that the increase of the spin orbit or spin flip electron scattering rates results in completely different transformations of $N(\varepsilon)$ at the free F layer interface. The developed formalism has been applied for the interpretation of the available experimental data.
