ABSTRACTWe present a calculation of spin waves in coupled multilayered structures which is based on exact evaluation of both exchange and dipolar fields. The ground state spin configuration in antiferromagnetically coupled multilayers can differ significantly from the uniformly canted ground state usually assumed. This non-uniform ground state is found to radically alter the character of the spin wave modes and sometimes lead to a strong localization of the wave to the outermost magnetic films of the Multilayer.

State Spin

We perform numerical simulations for the double exchange model. By minimizing the total energy, we obtain the ground state spin configuration and charge distribution as functions of electron density, the Hund's coupling JH, and the superexchange A. We present our studies for a wide range of parameters and also make comparison with the proposed canted and spiral phases.

Interlayer Exchange

ABSTRACTThe ground state spin configuration of antiferromagnetically coupled ferromagnetic thin films is determined by competition between anisotropies, interlayer exchange and the applied magnetic field. It is shown that many details of a ground state spin configuration can be obtained by studying the behavior of the spin wave frequencies as functions of propagation direction and applied field strength. A sensitive dependence on the relative film thicknesses is found for small applied field strengths.
