Abstract
For pt. I, see ibid., vol.21, p.1021 (1988). The general dispersion equations for bulk and surface magnetostatic modes in N-layered superlattices derived in the previous paper by the 'transfer matrix' method, are applied here to the cases of N=2 and N=3 different magnetic layers in an elementary unit. The layers are assumed to be magnetised parallel to the film planes and parallel to one another. Explicit forms of the 'transfer matrix' and of the dispersion equations for bulk and surface modes are given for propagation in the Voigt configuration. Numerical examples of the wave spectrum are presented for some superlattices composed of ferro magnetic, antiferromagnetic and nonmagnetic materials.
