Photoinduced irreversible change in an optical absorption a is observed for a bulk single crystal and a thin film of yttrium-iron garnets (YlG) over the spectral range 60001'700-2000 run and over the temperature range 80-200 K. In some specimens, coexistence of ph to induced and dark Lla-effectis found atlow temperatures. Experimental data are discussed within a simple phenomellological model .
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.
