DESCRIPTION:Prof. Manfred Fiebig\, ETHZ\nA reason for the interest in mul
 tiferroics is that magnetic and electric orders do not simply exist side b
 y side\, but exhibit "added value" in the form of magnetoelectric interact
 ions and functionalities between the ordered states. Likewise\, in a ferro
 ic material\, regions with different orientation of the order parameter\, 
 the domains\, do not simply exist side by side\, but they exhibit new phas
 es and properties in the domain walls. Because of their discontinuous\, co
 nfined\, and topological nature\, domain walls exhibit functional states t
 hat are not possible in the bulk. Continuing this line of thought\, one sh
 ould expect domain walls in multiferroics to be a particularly rich source
  of novel phenomena. Here one must distinguish between (i) "domain walls i
 n multiferroics"\, where only the ferroelectric (or magnetic) order is con
 sidered so that little is learned about the multiferroic state\, and (ii) 
 "multiferroic domain walls" where the ferroic phase coexistence of the wal
 l itself is of interest. The latter are rarely studied\, and I will discus
 s some of their intriguing features in my talk.\n\nBio: Professor Manfred
  Fiebig is known for his work in light-matter interaction in systems with 
 strong electronic correlations. (Multi-) ferroics are of particular intere
 st to him. After obtaining his doctoral degree in physics at the Universit
 y of Dortmund\, he worked at the University of Tokyo\, the Max Born Instit
 ut Berlin\, and the University of Bonn before he was appointed as Professo
 r of Multifunctional Ferroic Materials in the Department of Materials at E
 TH Zurich in 2011. In 2021 he also became a member of the National Researc
 h Council of the Swiss National Science Foundation (SNSF)\, and he was ele
 cted as Corresponding Member of the Academy of Sciences and Literature | M
 ainz. Most recent distinctions include the 2022 APS Frank Isakson Prize fo
 r Optical Effects in Solids as well as the of the Stern Gerlach Medal in 2
 023\, the highest distinction in Experimental Physics of the German Physic
 al Society. He is one of the founders of the ETH Spinoff Company “3Wave 
 Instruments”.
