Ferroic Materials for Transducers

The Ferroic Materials for Transducers (FMT) group studies and develops functional oxides, with a special interest on ABO₃ perovskite structures, which exhibit outstanding coupling properties. New intriguing physical effects are periodically discovered on this material family. Understanding these effects and using them in functional devices remains an internationally highly-competitive area and a great source of innovation. The main interest of ABO₃ perovskite structures is that their properties can be tuned and thus optimized to generate various devices with great performance and diverse functionalities, such as sensors and actuators.

The overall objective of our group is to acquire a broad knowledge of coupling phenomena in ferroic materials, with an aim of discovering new general concepts, clearing the way for both understanding and applications.
