Phase-resolved imaging of coherent phonon-magnon coupling
Yannik Kunz, Florian Kraft, David Breitbach +6
We use a direct phase-resolved optical technique to study the coherence of spin waves (SWs) that are driven by surface acoustic waves (SAWs) via resonant magnetoelastic coupling. F…
Spin-wave emission with current-controlled frequency by a PMA-based spin-Hall oscillator
Moritz Bechberger, David Breitbach, Abbas Koujok +4
Spin-torque and spin-Hall oscillators (SHOs) have emerged as promising candidates for building blocks in neuromorphic computing due to their ability to synchronize mutually, a proc…
An all-magnonic neuron with tunable fading memory
David Breitbach, Moritz Bechberger, Hanadi Mortada +9
Magnonics offers nanometer-scale wave propagation and strong nonlinearities, making it attractive for neuromorphic applications such as artificial neurons. Yet, magnonic elements w…
Three-dimensional nanoscale control of magnetism in crystalline Yttrium Iron Garnet
Valerio Levati, Matteo Vitali, Andrea Del Giacco +22
The exceptional magnetic, optical and phononic properties of Yttrium Iron Garnet (YIG) make it unique for spin-wave based and photonic applications. Yet, nanostructuring crystallin…
