Abstract:The knowledge of microwave intrinsic losses of ferrimagnetic single crystals is often obscured by the scattering process induced by surface defects. The existing data and the corresponding model dealing with this effect are far from sufficient to understand the phenomenon; in the millimetric range, the importance of the surface imperfection linewidth ΔHs is a major difficulty for obtaining the single-crystal intrinsic linewidth ΔHi from ΔH measurements. We have investigated on a pure YIG single crystal the ful… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
