Распространение спиновых волн в композитной структуре YIG/FeRh в виде системы связанных микроволноводов

In this paper present that it is possible to control the characteristics of spin waves (SW) in a system lateral magnetic waveguides made iron yttrium garnet (YIG) by changing antiferromagnetic iron-rhodium (FeRh) layer located above these waveguides. particular shown geometric parameters and magnetization FeRh one can amplitude phase SW propagating microwaveguides. The modes under which dips appear on transmittance amplitude-frequency response (AFR) due redistribution power are revealed, their location be controlled properties layer. results obtained used create microwave demultiplexers taps based proposed structure.
