摘要

提出了由多层铁氧体和介电层组成的结构中的准表面自旋电磁波谱理论。发达的理论考虑了不同铁氧体层中自旋波与电磁波之间的相互作用。结果表明，基于两层铁氧体膜和一层铁电层的铁氧体-铁电结构中的SEW光谱是由多次杂化形成的。发现在铁电薄膜中，由于自旋波的相互作用，在这些结构中仍然可以实现SEW的电调谐。

Numerical analysis of microwave excitations in multiferroic layered structures

We present a theory of quasi surface spin-electromagnetic waves (SEW) spectrum in structure consisting of multiple ferrite and dielectric layers. Developed theory takes into account interactions between spin waves in the different ferrite layers and electromagnetic waves. It was shown that SEW spectra in the ferrite-ferroelectric structure based on two ferrite films and one ferroelectric layer are formed by several hybridizations. It was found that electric tuning of SEW in these structures is still possible in case of thin ferroelectric film due to spin wave interaction.
