Аннотация: The energy gap appearing in the spin-wave spectrum as a result of Bragg scattering by the modulation period q = 2 pi/(d(1)+d(2)) Of a one-dimensional superlattice is observed by the method of spin-wave resonance in Co/Pd multilayer films. It is shown that this gap is asymmetric: The ''positive'' deviation is from two to three times greater than the ''negative'' deviation. (C) 1996 American Institute of Physics.
