Workshop
Grains, grain boundaries and magnetic domains
- Rudolf Schäfer (Leibniz Institute for Solid State and Materials Research Dresden)
Abstract
A review will be given on the role of grains and grain boundaries for the formation and behavior of magnetic domains and domains walls, based on experimental imaging by Kerr microscopy. The examples range from sintered and nanostructured permanent magnets to coarse grained- and nanocrystalline soft magnets. The role of grain boundary orientation for flux propagation as well a homogenization effects in nanocrystalline material will be addressed.
