The article is devoted to the investigation of electric properties of ferroelectric-semiconducting AgPbAsSe 3 at pressures up to 45 GPa and the existence of phase transitions in this compound. Our data show that there are two phase transitions at 1.5-2 and 31-32 GPa.
The pressure dependences of electrical resistance, Hall coefficient, charge carrier mobilities, and magnetoresistance of the Cd 3 As 2 -20 mol % MnAs composite are investigated at pressures up to 9 GPa. The pressure dependences of all the listed properties exhibit features related to phase transitions. The presence of pressure-induced negative magnetoresistance is registered.
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.
