SYMS: Symposium Novel phases and dynamical properties of magnetic skyrmions

SYMS 1: Novel phases and dynamical properties of magnetic skyrmions

Dienstag, 28. September 2021, 10:00–12:45, Audimax 2

The discovery of skyrmions in cubic chiral ferromagnets over a decade ago, featuring non-trivial topological winding and greatly enhanced sensitivity to spin transfer torques, stimulated intense research into the suitability of skyrmions for technical applications. The symposium focusses on the recent identification of symmetry-broken phases and new forms of driven dynamical states of skyrmions in ferromagnetic host materials vis a vis the discovery of skyrmionic order in geometrically frustrated and antiferromagnetic magnets and their dynamical properties. The symposium this way highlights the intimate relationship of non-trivial topology and exceptional spin dynamics in different skyrmion-hosting systems.
