KFM 1: Focus Session I: Ferroics - Domains and Domain Walls

Dienstag, 28. September 2021, 10:00–12:45, H2

The Focus Sessions: Ferroics - Domains and Domain Walls is dedicated to the detection of multiferroic and ferroelectric domain pattern, their manipulation as well as the modeling of domains. These domains and domain walls are fascinating building blocks for novel (nanoscale) electronics ranging from switches, memristive elements towards diodes and reconfigurable wires.

Chairman: Stephan Krohns (University of Augsburg)
