Abstract
An investigation of the angular dependence of the dynamic permeability spectra has been performed. Three Permalloy films with different thickness were used as the study samples that possess the stripe domains. In order to better understand the magnetization distribution in stripe domains, a theoretical approach was proposed to analyze the variation of the resonance intensity of permeability spectra. By fitting the angular dependence of the μâ³max using a theoretical function, a coefficient Î that can be used to evaluate the average value of the periodic function of the anting angle θ in a periodic stripe is obtained. As the film thickness increases, the decrease of the ratio between domain wall width and stripe domain width is happen. This enables that the coefficient Î decreases with the increase of film thickness. By deducing this coefficient Î, one can estimate the maximum canting angle θ0 â¼Â 8° for the Permalloy films in our experiments.
