Here we present evidence for piezoelectricity and antiferromagnetic ordering in a multifunctional material PbV O3. Through the use of second-harmonic generation and x-ray linear dichroism, we determine a transition from a polar-only 4mm state to a polar and magnetic state below ∼100-130 K. In combination with theory, the magnetic symmetry has been narrowed to be G type (4′/m′ m m′) or spin glass. An effective piezoelectric coefficient of d33 ∼3.1 pC/N was also measured in the polar state at room temperature. © 2007 The American Physical Society.}, year = {2007}, journal = {Physical Review B - Condensed Matter and Materials Physics}, volume = {75}, number = {6}, issn = {10980121}, doi = {10.1103/PhysRevB.75.060101}, note = {cited By 38}, language = {eng}, }
