Spin wave propagation in perpendicular magnetized 20 nm Yttrium Iron Garnet with different antenna design

POSTER

Abstract

Magnonics offers a new way to transport information using spin waves free of charge current and could lead to a new paradigm in the area of computing. Forward volume (FV) mode spin wave with perpendicular magnetized configuration is suitable for spin wave logic device because it is free of non-reciprocity effect. Here, we study FV mode spin wave propagation in YIG thin film with an ultra-low damping. We integrated differently designed antenna i.e., coplanar waveguide and micro stripline with different dimensions. The $k$ vectors of the spin waves defined by the design of the antenna are calculated using Fourier transform. We show FV mode spin wave propagation results by measuring S$_{\mathrm{12}}$ parameter from vector network analyzer and we extract the group velocity of the FV mode spin wave as well as its dispersion relations.
