Notes:
A scanning x-ray microscope using circularly polarized radiation has been constructed at the beamline NE1B of the 6.5-GeV TRISTAN accumulation ring (AR). It uses a Fresnel zone plate as an x-ray focusing lens. Its spatial resolution has been evaluated to be ∼1.2 μm at the energy of 933 eV. Depending on the relative orientation between the photon spin and the local magnetization direction, the magnetic domains recorded in a piece of videotape have been successfully observed visually at the L2,3 absorption edges of cobalt. The contrast of the image arises from the magnetic circular dichroism in core-level photoemission of ferromagnets. The observed contrast was certainly reversed between L2 and L3 edges. © 1995 American Institute of Physics.
