The field of functional thin films has transformed in the past decade. This is
due to the development of experimental techniques that allow synthesizing
materials with atomic control, which eventually leads to atomically-defined
interfaces, showing the way to much improved devices and, in some cases, to
totally new device concepts. Here I will focus on the challenges related to
the synthesis and characterization of ferroic thin films, particularly of
oxide thin films, and the ordering phenomena responsible for their large and
tunable electrical, mechanical or magnetic responses, which are directly
linked to their ferroelectric, ferroelastic or magnetic nature. I will discuss
the role of epitaxy on the atomic structure (strain engineering) but also on
the microstructure and properties. I will illustrate this with examples of our
own work on ferroelectric/piezoelectric PZT and BaTiO3, multiferroic TbMnO3
and BiFeO3 or our most recent work on the newly discovered (by the Namlab team
in Dresden) nano-ferroelectric Hf0.5Zr0.5O2. Finally, I will offer my vision
about future directions in the field of (multi)ferroic oxides.
