Abstract

By using photoelectron emission microscopy, we systematically investigated the magnetic domain in the La0.6 Sr0.4 Mn O3 patterned thin film with several microns, in which we can control the ratio of a shape anisotropy to a step-induced uniaxial anisotropy in magnitude. We demonstrate that a cooperative effect of a step-induced uniaxial anisotropy with a shape anisotropy causes the formation of a single domain, whereas the competitive effect makes a multimagnetic domain.
