Abstract

This work examines the impact of electromagnetic crosstalk in magnonic devices when using inductive spin-wave (SW) transducers. We present detailed electrical SW spectroscopy measurements showing the signal contributions to be considered in magnonic device design. We further provide a rule-of-thumb estimation for the crosstalk responsible for the secondary SW excitation at the output transducer. Simulations and calibrated electrical characterizations underpin this method. In addition, we visualize the secondary SW excitation via time-resolved magneto-optical Kerr effect (trMOKE) imaging in the forward-volume (FV) configuration in a 100 nm yttrium-iron-garnet (YIG) system.
