Steerable Volume and Surface Spin Waves in Ferrimagnetic Films
Abstract
This report describes in detail the technical progress made during the third six months of a three year interdisciplinary research program. One major goal of the program is the growth of yttrium-iron garnet (YIG), single crystals of high quality in both thin film and bulk form. Another is the development of novel techniques for controlling and studying energy propagation characteristics of volume and surface spin waves. One promising technique for accomplishing the former is the use of chemical vapor deposition (CVD) and cumulative progress with this method is recounted fully. The latter goal is being met by a combination of optical and microwave techniques used to probe the dynamics of spin wave propagation. The optical experiments were described in the last semi annual report; microwave propagation studies of magnetostatic surface spin waves in YIG slabs are presented in this report.
