Propagating spin waves in YIG micro-channel on Silicon
POSTER
Abstract
Recently the utilization of spin waves in the field of information processing has been widely developed because it is free of Joule heat dissipation and beneficial to miniaturization of the magnon based devices. Here we study spin waves in yttrium iron garnet (YIG) with a low damping property. The YIG film is fabricated on silicon substrate using pulsed laser deposition and the measured FMR linewidth is only a few Gauss. Using ebeam lithography, we are able to pattern the YIG film into a micro-channel and integrate sub-meter waveguides to generate and detect spin waves of wavelength down to 1$\mu$m or below. We show results of propagating spin waves in the YIG micro-channel measured by the $S_{12}$ parameter of the vector network analyzer.
