Abstract

Images of a thin film permalloy element taken with Lorentz and magnetic force microscopies are compared with those from a simulation of the expected magnetic structure of the element. Measurements taken from the domain walls present in the element allow a quantitative comparison to be made. In the case of magnetic force microscopy, quantification is made possible by using a nonperturbative approach based on an extended charge model for the magnetic probe. Excellent agreement between experiment and simulation is observed for both imaging techniques.
