Abstract: We have studied finite and infinite ferromagnetic/nonmagnetic superlattices in which the surface layer has a different magnetization. The magnetostatic limit is used, and the magnetic potentials in any region are obtained by solving recurrence relations. The equation giving the frequency for all the spin waves for a finite system is derived. It is shown that in the infinite limit, in addition to the usual Damon and Eshbach mode, two additional surface modes appear when the surface magnetization is larger than the host one. The finite results for eight layers are also shown. © 1994 The American Physical Society.
