Implication

Experimental and numerical analysis reveals finite permeability effects in thin Permalloy I bars, indicating limitations in previous indirect magnetization models.

Key Points

To calculate and measure the impact of finite material permeability on the magnetization profile of thin Permalloy I bars in bubble circuits.
Applied a new direct calculation method to evaluate the magnetization profile in an isolated thin Permalloy I bar across varying susceptibility limits.
Conducted experimental measurements on sparse arrays of Permalloy I bars using a large-area magneto-optic probe.
Compared direct calculation results against empirical probe data, previously published indirect calculations, and self-consistent field (SFS) models.
Identified that the scale factor utilized in previous indirect calculations is approximately 8% too high in the theoretical limit of infinite susceptibility.
Observed worsening discrepancies between indirect models and direct calculations when evaluated at lower material susceptibility values.
