We show that a BiAg surface alloy grown on a thin ﬁlm of Ag leads to the interplay between the electronic states of the surface alloy and the quantum well states developing in the Ag layer. This interaction produces a set of spin-split bands and leads also to openings of spin-dependent gaps in the band structure.
