  Influence of a nonmagnetic surface on the density of states in a spin-split
superconductor, which is realized on the basis of a S/F bilayer, is
investigated. It is demonstrated that if the ferromagnet magnetization has a
defect in the form of a domain wall in the vicinity of the surface, the
superconducting density of states is reconstructed manifesting the spin-split
Andreev resonances. Formation of these resonances is not connected to any
superconducting order parameter inhomogeneities. Andreev reflection processes
forming the resonances occur at the inhomogeneity of the spin-split gap
generated by the domain wall. These resonances can be used as a spectroscopic
probe of a domain wall presence and motion.
