Abstract :
Lead magnesium niobate/lead titanate solid solutions with lanthanum dopants show substantial promise as electromechanical materials. In this work, the capacitance, dielectric loss, polarization, and transverse strain measurements of such materials are reported. These data are then matched with a model to predict the bulk coupling coefficient. This characterization avoids the problem of explicitly linearizing the electromechanical response of an electrostrictive material
