Abstract
Magnetic domains on an Fe(100) surface have been imaged by means of energy-resolved photoemission microscopy. We excited the photoelectrons with circularly polarized synchrotron radiation in the soft x-ray region, and employed the effect of magnetic circular dichroism in the emitted photoelectrons in order to obtain contrast between differently oriented magnetic domains. This new approach offers a surface sensitive way to combine chemical and magnetic information on a microscopic scale.
