In SrF2 crystal doped with Cr 2+ ions, attenuation of all the normal ultrasonic modes with the wave vector k < 110 > were investigated at 52-162 MHz in the temperature region of 4-180 K. The observed peaks of relaxation origin were interpreted as manifestation of the Jahn-Teller effect.
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.
