In situ magnetic domain imaging — •Dietrich Peterka, Günter Haas, and Klaus Kern — Max-Planck-Institut für Festkörperforschung, D-70569 Stuttgart
The magnetic properties of thin ferromagnetic films often differ from the bulk material behavior. For the system Fe/Cu(100) several phenomena have been observed, e.g. a reduction of the Curie temperature as well as a magnetisation reorientation from in-plane to out of plane orientation. We have constructed a variable temperature Magnetic Force Microscope to study the micromagnetic structure of well-defined thin film systems. The instrument works in UHV and allows to change the tip in-situ. The chamber is also equipped with sample preparation and analysis methods as well as a Kerr microscope. In this apparatus samples can be grown and studied in-situ under well controlled conditions. The combination of the two microscopy methods allows to image magnetic domain patterns over a wide range of length scales. We will present first results for the system Fe/Cu(100).
