Magnetization Reversal in an Fe Film with an Array of Elliptical Holes on a Square Lattice
Abstract
The reversal mechanism for the magnetization in an Fe film with an array of elliptical holes is investigated using the diffracted magneto-optic Kerr effect (D-MOKE) technique. D-MOKE results are obtained as a function of temperature and the angle between the applied magnetic field and an ellipse axis. The transverse and longitudinal magnetization components and minor magnetization loops are also explored in order to understand the reversal process. The experimental results are interpreted using micromagnetic simulations. The simulations account for the strong angular dependence of the hysteresis loops and provide a detailed picture of how the local magnetization evolves during reversal. The actual reversal process occurs neither by coherent rotation of domains nor by clear domain-wall motion: domain smearing appears to be a more suitable description of the phenomenon.
