<jats:title>Abstract</jats:title><jats:p>Thin <jats:italic>S</jats:italic> = 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<jats:sub>c</jats:sub> parameter for the thin film case is also proposed.</jats:p>
