Abstract

Low energy domains in soft ferromagnetic films were discussed. Computations based on two-dimensional model were used to study the experimental observations of permalloy films under in-plane applied magnetic fields. It was found that the magnetic charge density or the magnetization in the regions of film where the external field penetrated the sample could be computed easily by energy minimization and were less prone to hysteresis than the underlying domain structures.
