Abstract

Topological structures in ferroic functional materials, such as domain walls and skyrmions, currently see increased attention due to their intriguing properties and application potential in nanoelectronics [1]. I will discuss some of our recent results on ferroelastic, ferroelectric and multiferroic materials systems [2, 3, 4, 5, 6] using scanning probe microscopy as the main investigative tool, which is combined with insight from electron microscopy and ab-initio theory, and discuss future prospects of this quickly evolving research field.
