    • The parameter J in Eq. (1) should not be confused with the pair interaction energy commonly used to describe the nearest-neighbor exchange energy between localized spins. In the notation used in Ref. 2, J=(4AAB/a) where AAB is an interface exchange stiffness parameter and a is the bcc lattice cube edge.

    • The FMR absorption becomes very small for identical films whose thicknesses are small compared with the microwave skin depth. The BLS scattering intensities become very small for films having identical magnetic properties and which are thin compared with the optical skin depth.

    • A calculation has been carried through for a 5-ML Fe film [ curlep =(-0.4 +i16.41)] deposited on a Ag substrate [ curlep =(-10.66 +i0.33)], then followed by 12 ML of Cu [we have used curlep =(-5.33+i6.18) appropriate for fcc Cu], 10 ML of Fe, and covered by 20 ML of Au [ curlep =(-3.75+i2.75)]. The electric-field amplitude decreased by approximately 6% across the 10-ML iron film and by approximately 2% across the 5-ML iron film. The discontinuity in the electric-field amplitude between the rear surface of the 10-ML film and the front surface of the 5-ML film was calculated to be 7%. Dielectric constants for 5145-Å light were obtained from Johnson and Christy (Refs. 34 and 35) for Ag, Cu, and Fe, and from Joensen et al.. (Ref. 36) for Au.

    • Positive q corresponds to scattered light whose frequency has been increased by the magnon frequency; negative q corresponds to scattered light whose frequency has been decreased by the magnon frequency.
