Magnetostatic spin waves in a multilayer film consisting of two magnetic co
nductive layers separated by a nonmagnetic conductor are analyzed. Two magn
etostatic spin wave branches are shown to exist and their dispesion laws ar
e analyzed. Structures of finite width, which are relevant for device appli
cations, are also considered. (C) 2000 Elsevier Science B.V. All rights res
