Abstract
Abstract Oriented iron islands of rectangular shape on tungsten were created by self-organization. These systems have been analyzed by Scanning Tunneling Microscopy (STM) with respect to their shape and concerning their electronic and magnetic behavior with angle resolved photoemission using polarized synchrotron radiation in the soft X-ray region. The magnetic information can be obtained by the technique of Magnetic Linear Dichroism in the Angular Distribution of photoelectrons (MLDAD). Furthermore, an array of iron dots on tungsten has been studied with photoemission electron microscopy (PEEM). Element-specific information is available via the characteristic absorption levels (using the tuneable synchrotron radiation) or by threshold photoemission using a mercury lamp due to the different work functions. Circularly polarized radiation enables the observation of magnetic domains.
