Spin waves, the elementary low energy excitations of an ordered spin system, and their bosonic quanta, magnons, carry energy and angular momentum in the form of spin. The field of magnonics aims to create devices for sensing, data processing and logic which are based on spin waves and their outstanding properties like intrinsic nonlinearity and nanometer wavelengths at GHz frequencies.

Our scientific aim is to explore and combine emerging physical phenomena which can be used to realise novel magnonic hybrid systems with novel and superior characteristics. We have a particular focus on:

  • Nonlinear spin-wave phenomena in micro- and nanostructures
  • Nanoscaled magnonic devices for unconventional data processing
  • Novel materials for magnonics including low-damping Heuler compounds
  • Hybrid systems combining magnonics with spintronic and phononic systems
  • Amplification and control of coherent spin-waves in micro-and nanostructures using parametric processes
  • Nonreciprocal magnonic systems based on dipole-dipole and DMI interactions

To achieve our goals, we investigate magnonics systems experimentally by Brillouin light scattering spectroscopy and inductive techniques. To study and optimize magnonic systems before fabrication, we employ massively parallelized micromagnetic simulations. These simulations are run and analysed by our home-made AITHERICON software platform with the aim to use artificial intelligence, neural networks and inverse design methods to create magnonic systems with designed and superior properties for wave-based transport and data processing.
