If in Maxwell equation =0, the retarded modes will transite to ferromagnetic/ferromagnetic superlattice magnetostatic modes. 1.Introduction Layered magnetic materials in the spin-wave excitation is the cohesion more interested in the physical state of one of the research.
In recent years, people of such materials in the spin-wave Spectrum [1], dispersion relations [2], spin resonance wave [3], since Spin wave nature of the [4] and a variety of spin-wave mode [5], As well as the band structure [6,7] and other issues, reasonable on the experimental side and made a large number of studies [8,9,10].
We found that magnetic not only in the superlattice structure with greater control sex (such as composition, thickness, thickness ratio) is more important in the presence of these materials, some of the original material does not have the effect and nature of the new.
