Skyrmions for reservoir computing — •Karin Everschor-Sitte — Institute of Physics, Johannes Gutenberg-University Mainz

The topological properties of magnetic skyrmions, their inherent compact particle-like nature and their complex and nonlinear dynamics make skyrmions interesting for spintronics applications and in particular unconventional computing schemes. [1] In this talk I will address the potential of magnetic skyrmions for reservoir computing, i.e. a computational scheme which allows to drastically simplify spatial-temporal recognition tasks. We have shown that random skyrmion fabrics provide a suitable physical implementation of the reservoir [2,3] and allow to classify patterns via their complex resistance responses either by tracing the signal over time or by a single spatially resolved measurement.
