Research Abstract

Magnonic crystals comprising yttrium iron garnet (YIG) with the periodic change of conductivity can control the propagation properties of spin waves. We investigated the fundamental properties on the controllability of spin wave by magnonic crystals. For instance, single defect was introduced into the magnonic crystals and generated the localization mode of spin waves. This phenomenon was applied to the magnonic sensors. And also, the novel processes, nano-scale materials, and new device structures to improve the quality factor of the sensors were developed. These results were reported in journals and academic symposiums.
