Recent topics in multilayer studies relating to surface anisotropy are introduced. In Fe/Mg and Mn/Sb multilayers, ferromagnetic monolayer samples were fabricated, which show perpendicular easy directions but have lower Tc than room temperature. It was found that Co/Pt multilayers have a potentiality as magnetic recording media since their perpendicular magnetization is stable at room temperature. The giant magnetoresistance found in Fe/Cr multilayers is another recent topic in this field.
