We studied the crystallographic, magnetic, optical and microwave propagation properties of fibrous rare-earth-substituted Y2.7R0.3Fe5O12 (R:YIG) single crystals, grown by a simple floating
zone (FZ) method with yttrium aluminium garnet (YAG) laser heating assisted by infrared
irradiation, for all rare-earth elements. The first purpose of our studies was to seek outstanding
properties of R:YIG crystals and the second aim was to obtain data in order to develop crystals with
complex properties, such as large Faraday rotation and low saturation magnetization, by
substituting two or more rare-earth elements for Y into the YIG crystal. The lattice constant,
saturation magnetization, Faraday rotation, optical absorption coefficient, full-width at half
aximum (ΔH) of ferromagnetic resonance and microwave propagation in magnetostatic wave (MSW) modes were measured for R:YIG single crystals. Low saturation magnetization in Gd:YIG and Tb:YIG, large Faraday rotation in Ce:YIG and low loss propagation of MSW in Lu:YIG were
found. Our comprehensive results will also contribute to identifying
new materials applicable in for optical and microwave devices
utilizing R:YIG crystals.
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.
