Establishing the Magnetoelastic Origin of Spin-Wave Routing through Focused Ion Beam Patterning
Felix Naunheimer, Johannes Greil, Valentin Ahrens +4
Spin waves are promising information carriers for analog and wave-based computing, where functionality relies on compact and precisely engineered scattering landscapes. Focused ion…
Secondary Excitation of Spin-Waves: How Electromagnetic Cross-Talk Impacts on Magnonic Devices
Johannes Greil, Matthias Golibrzuch, Martina Kiechle +4
This work examines the impact of electromagnetic cross-talk in magnonic devices when using inductive spin-wave (SW) transducers. We present detailed electrical SW spectroscopy meas…
Experimental Demonstration of a Spin-Wave Lens Designed with Machine Learning
Martina Kiechle, Levente Maucha, Valentin Ahrens +5
We present the design and experimental realization of a device that acts like a spin-wave lens i.e., it focuses spin waves to a specified location. The structure of the lens does n…
Spin-Wave Optics in YIG by Ion-Beam Irradiation
Martina Kiechle, Adam Papp, Simon Mendisch +6
We demonstrate direct focused ion beam (FIB) writing as an enabling technology for realizing spin-wave-optics devices. It is shown that ion-beam irradiation changes the characteris…
Experimental Demonstration of a Rowland Spectrometer for Spin Waves
Adam Papp, Martina Kiechle, Simon Mendisch +6
We experimentally demonstrate the operation of a spin-wave Rowland spectrometer. In the proposed device geometry, spin waves are coherently excited on a diffraction grating and for…
Robust formation of nanoscale magnetic skyrmions in easy-plane thin film multilayers with low damping
Luis Flacke, Valentin Ahrens, Simon Mendisch +14
We experimentally demonstrate the formation of room-temperature skyrmions with radii of about 25\,nm in easy-plane anisotropy multilayers with interfacial Dzyaloshinskii-Moriya int…
Controlling Domain-Wall Nucleation in Ta/CoFeB/MgO Nanomagnets via Local Ga+ Ion Irradiation
Simon Mendisch, Fabrizio Riente, Valentin Ahrens +6
Comprehensive control of the domain wall nucleation process is crucial for spin-based emerging technologies ranging from random-access and storage-class memories over domain-wall l…
