Non-reciprocal spin wave beams in thin magnetic films

Résumé

We present several approaches that allows exciting non-reciprocal spin wave beams in thin magnetic films. Using primarily the spin wave spectroscopy techniques performed in both in-and out-of-plane geometries, we show that the spin wave beamforming can be tailored using concepts inspired from optics. We also developed a near-field diffraction model that benchmarks spin wave diffraction in thin films for any geometry, and is readily applicable for future designs of magnon interferometric devices. Magnonic devices, which take advantage of the versatility of spin waves, are anticipated to be a propitious alternative for efficient signal processing. Spin waves constitute the building blocks of novel wave computing methods such as spectral analysis [1], and neuromorphic computing [2], which are all interference based
