The mechanism used to alter the features of propagating spin waves is a key component underpinning the functionality of high frequency magnonic devices. Here, using experiment and micromagnetic simulations, we demonstrate the feasibility of a magnonic multiplexer in which the spin-wave beam is toggled between device output branches by the polarity of a small global bias magnetic field. Due to the anisotropy inherent to the dispersion of magnetostatic spin waves, the phase fronts of the output spin waves are asymmetrically tilted relative to the direction of the beam propagation (group velocity). We show how the phase tilts could be (partly) rectified in magnonic waveguides of variable width.

This is the author accepted manuscript. The final version is available from IEEE via the DOI in this record.
The attached '.mif' files are designed for use with the micromagnetic simulation tool 'Object-Oriented Micro-Magnetic Framework' (OOMMF). The software release, along with a user's guide, is free to download at http://math.nist.gov/oommf/. To use the '.mif' files, first load and run the '*relaxation.mif' script. Then, once this simulation has finished, rename the new '*.omf' file to 'Relaxed.omf', and then run the '*pulse.mif' script.
