Introduction to ferroic materials — •Claude Ederer — Materials Theory, ETH Zürich, Switzerland
In this tutorial talk I will give a general introduction to the physics of ferroic materials. I will discuss different cases such as ferro- and antiferromagnets, ferroelectrics, ferroelastics, and multiferroics. The basic phenomenology of ferroics will be introduced on the level of Landau theory, which allows to distinguish proper and improper ferroics and also to describe possible coupling between different ferroic order parameters. The important role of symmetry will be highlighted and microscopic mechanisms that drive the formation of ferroic orders will be mentioned.
