Abstract
A model for analyzing the Permalloy circuits in magnetic bubble domain field access devices is presented. The model is numerical in nature and an iterative scheme is used to determine the magnetization distribution in the Permalloy. The model, which includes bubble-Permalloy interaction, is capable of handling any arbitrary Permalloy shape in two dimensions and hence a wide variety of bubble circuits can be analyzed. An algorithm for computing bubble size fluctuations is presented. Comparison to experimental data shows very good agreement.
