Chiral Excitation of Exchange Spin Waves Using Gold Nanowire Grating

Chiral Excitation of Exchange Spin Waves Using Gold Nanowire Grating

We propose an experimental method for the unidirectional excitation of spin waves. By structuring Au nanowire arrays within a coplanar waveguide onto a thin yttrium iron garnet (YIG) film, we observe a chiral coupling between the excitation field geometry of the nanowire grating and several well-res...
