The Effect of Ga-Ion Irradiation on Sub-Micron-Wavelength Spin Waves in Yttrium-Iron-Garnet Films
Johannes Greil, Martina Kiechle, Adam Papp +8
We investigate the effect of focused-ion-beam (FIB) irradiation on spin waves with sub-micron wavelengths in Yttrium-Iron-Garnet (YIG) films. Time-resolved scanning transmission X-…
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…
Model-based learning of local image features for unsupervised texture segmentation
Martin Kiechle, Martin Storath, Andreas Weinmann +1
Features that capture well the textural patterns of a certain class of images are crucial for the performance of texture segmentation methods. The manual selection of features or d…
A Bimodal Co-Sparse Analysis Model for Image Processing
Martin Kiechle, Tim Habigt, Simon Hawe +1
The success of many computer vision tasks lies in the ability to exploit the interdependency between different image modalities such as intensity and depth. Fusing corresponding in…
