Magnetostatic spin waves in metallic multilayers

• Magnetostatic spin waves in a multilayer film consisting of two magnetic conductive layers separated by a nonmagnetic conductor are analyzed. Two magnetostatic spin wave branches are shown to exist and their dispesion laws are analyzed. Structures of finite width, which are relevant for device applications, are also considered.
