Abstract text

As materials that display functional (such as magnetic and electronic) behavior are patterned at the nanoscale, so novel emergent behavior can arise as a result of confinement and as a result of the proximity of different materials at interfaces. It is critical to explore the local behavior of the materials and to correlate this behavior with structure and chemistry. In-situ electron microscopy is an excellent tool for exploring such materials since it is possible to image the spatial distribution of the magnetic and electric fields that contribute to the novel behavior, as a function of external stimuli such as applied fields and temperatures. Examples of recent materials of interest include 2D materials that display a range of novel properties including supporting chiral magnetic spin structures such as skyrmions, and resistive switching materials based on phase transitions or oxygen vacancy transport. In this presentation we will discuss the application of a range of in-situ electron microscopy techniques to exploring the novel behavior of such materials.
