A highly topical set of perovskite oxides are high-sensitivity piezoelectric ones, among which
Pb (Zr, Ti) O 3 at the morphotropic phase boundary (MPB) between ferroelectric
rhombohedral and tetragonal polymorphic phases is reckoned a case study. Piezoelectric
ceramics are used in a wide range of mature, electromechanical transduction technologies
like piezoelectric sensors, actuators and ultrasound generation, to name only a few
examples, and more recently for demonstrating novel applications like magnetoelectric …

Magnetoelectric composites are a unique category of materials that are sought after for
diverse applications owing to their versatile properties. The magnetoelectric effect that is
dominant in these materials enables them to be candidate materials for applications in the
fields of biomedical engineering, electronics engineering, and materials technology. This
chapter aims to provide an introduction to the magnetoelectric effect by presenting its
historical background and theoretical considerations. The key factors that influence the …
