FM 3: Focus Session: Novel mechanisms of ferroic switching (joint session MA/FM)
Montag, 9. März 2026, 09:30–12:00, POT/0151
This focus session highlights recent advances in ferroic switching across ferroelectric, multiferroic, ferroaxial and magnetic systems. Topics include topologically protected order-parameter dynamics, ultrafast non-thermal switching, and complex domain-wall phenomena revealed by atomistic modeling, ultrafast optics and advanced imaging. Contributions span machine-learning-based simulations of domain kinetics, optical control of ferroaxial and structural orders, multiferroic multi-cell memory concepts, and theoretically predicted unidirectional domain-wall motion with time-crystal behavior. Together, these works uncover new switching pathways and robust functional mechanisms, offering promising routes toward energy-efficient memory and quantum devices.
