Ferroelectrics and multiferroics

Ferroelectrics and multiferroics are a class of materials that exhibit switching of their physical properties under an external influence. Ferroelectrics demonstrate a switchable electric polarization when an electric field is applied. Multiferroics exhibit a similar ‘ferroic’ behaviour in two or more of their (usually electric, magnetic or elastic) properties.

    Topological structures have considerable potential in nanoelectronics and new device concepts. They are key to the design and understanding of novel functionalities in ferroic materials — that is, materials that have one or more types of built-in order such as magnetic, ferroelectric, ferroelastic and multiferroic materials.
