Title: Polar and magnetic properties of pbvo3 thin films

Abstract

Multifunctional materials promise to provide the foundationfor a class of devices in which electrical, magnetic, elastic, and otherproperties are coupled to one another. Here we present evidence forpiezoelectricity and antiferromagnetic ordering in a multifunctionalmaterial PbVO3. Through the use of second-harmonic generation and x-raylinear dichroism, we determine a transition from a polar-only 4mm stateto a polar and magnetic state below ~;100-130K. In combination withtheory, the magnetic symmetry has been narrowed to be G type (4'/m'mm')or spin glass. An effective piezoelectric coefficient of d33 ~; 3.1pC/Nwas also measured in the polar state at room temperature.
