We have investigated the influence of the electric bias field on the magnetic and transport properties of (011)-oriented La 0.9 Ba 0.1 MnO 3 (LBMO) thin film epitaxially grown on (011)-0.7Pb(Mg 1/3 Nb 2/3 )O 3 -0.3PbTiO 3 (PMN-PT) single crystal substrate. It was found that strain and polarization effects induced by electric bias coexist in the whole temperature range and both of them can modulate the transport properties of (011)-LBMO on PMN-PT. The relative change of resistance DR/R exhibits peak values of À22% and À32% for bias fields of þ12 and À12 kV/cm, respectively, around metal-insulator transition temperature, T MI . However, the sign of DR/R shows polarity dependence at temperature far below T MI . Further careful analysis demonstrates that these two opposite behaviors can be ascribed to the different influence of strain and polarization effects on transport properties.
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.
