Abstract:
A scanning-aperture electron microscope, comprising:a radiation source generating a radiation beam;a polarization rotator polarization modulating the radiation beam, the polarization-modulated radiation beam being incident upon a surface of a sample material causing electrons to be ejected from the material, the sample material having at least one magnetic domain, the ejected electrons being ejected from the surface of the sample material in accordance with a polarization of the radiation beam that is incident upon the surface of the sample material and a relative orientation of each magnetic domain;a scanning-aperture probe having an aperture, the aperture being positioned in proximity to the surface of the sample material so that electrons ejected from the surface of the sample material pass through the aperture; andan electron detector detecting the ejected electrons passing through the aperture.
