Thickness dependence of spin wave dynamics in three-fold nano-ellipse clusters
Abstract
We present the results of an experimental and theoretical study of spin wave dynamics in three-fold vertices made of permalloy nano-ellipses, with thicknesses ranging from 7.5 nm to 40 nm. For the most symmetric modes, a non-trivial variation of their frequency and intensity with the ellipse thickness is found. Simulations involving the dynamical matrix approach are in good agreement with the experiments.
