TT 60: Focus Session: Topological Defects in Superconductors and Magnets (joint session TT/MA)

Wednesday, March 14, 2018, 15:00–17:45, H 0104

Vortices in superconductors and skyrmions in magnets are two examples of topological objects that can form a lattice and have particle-like properties. Their orientation and symmetry is determined by the magnetic field and the interaction within the material. The scientific and methodological approaches are similar*both can be studied using transport and magnetization and both can be observed using neutron scattering and scanning microscopies. Nanofabrication, often with the help of hybrid structures, allows controlling and manipulating them. The latter is believed to play a key role in applications involving current carrying and magnetic memory devices. The aim of the colloquium is to present most recent advances with a particular focus on the cross-fertilization of research on topological defects in superconductivity and magnetism.
