Thin S = 1/2 ferromagnetic film with exchange interaction enhanced near the film surface is considered in the Ising model. As a result the phase diagrams, the magnetization profiles, and magnetization curves for several particular cases are presented. A modified definition of the critical δ c parameter for the thin film case is also proposed.
