ABSTRACT
A Faraday magneto-optical effect filter has been developed to convert linearly to elliptically polarized undulator radiation to provide magnetic circular dichroism (intensity) contrast from magnetic samples in an existing scanning transmission x-ray microscope. Strong magnetic contrast is observed across a 180° domain wall in a 33 nm thick demagnetized Fe film with in-plane magnetization, and clear structure is associated with the domain wall. By rotating the sample through large angles, magnetization components normal to the film are clearly observed and are associated with the domain wall structure, confirming that it is a cross-tie wall. Strengths and weaknesses of this approach compared to others are discussed.
