Structure-property relations in multifunctional bismuth ferrite - lead titanate

Abstract

Solid solutions of bismuth ferrite - lead titanate are proving to be of interest for a number of applications due to not only the potential for room temperature magnetoelectric coupling, but also due to the anomalous combination of large spontaneous strain and high Curie temperature at the morphotropic phase boundary. Here we report on progress in the magnetic characterization, the development of high temperature piezoelectric devices and the characterization of thin films for FeRAM applications.
