KFM 1: (Multi)ferroic States: From Fundamentals to Applications (I)

Monday, March 17, 2025, 09:30–11:15, H9

This focus session explores the intricate properties of (multi)ferroic states, spanning from fundamental understanding to cutting-edge applications. Topics include the design and control of (multi)ferroic states and domain structures at interfaces, domain walls, and in heterostructures. Emphasis will be placed on theoretical models, advanced characterization techniques, and the engineering of emergent properties for use in nano-electronic devices.

Chair: Johanna Nordlander (University of Zurich)
