Modeling magnetization curves in magnetic thin films with striped patterns

Abstract : In this work, we study magnetic thin films presenting magnetic stripe patterns. A fingerprint of such domains is a linear behavior of the in-plane magnetization curves below a given saturation field. We present free energy models for the in-plane magnetization curves which permit us to extract key geometrical information about the stripe patterns, such as the maximum canted angle of the magnetization and the domain wall width. As an example, we discuss in this work magnetization curves for Fe1-xGax magnetic films which present a stripe pattern with a period of 160 nm and we found a typical maximum canted angle of 85 degrees and a domain wall width around 30 nm.
