ABSTRACT
We report on a scanning near-field optical microscope which operates in ultrahigh vacuum and allows magneto-optical Kerr-effect measurements at variable temperatures and in external magnetic fields with subwavelength lateral resolution. High magneto-optical contrast is achieved by combination with a Sagnac interferometer. In this way, magnetic domain patterns of ultrathin films of Fe/Cu(100), grown at 80 K, were studied in situ. A domain phase consisting of perpendicularly magnetized submicron wide stripes with directional order was observed. © 2003 American Institute of Physics.
