    Brookhaven Lab physicists Claudio Mazzoli (left) and Mark Dean at the Coherent Soft X-ray Scattering (CSX) beamline at the National Synchrotron Light Source II. Mazzoli and Dean are part of the team of scientists led by Rutgers University that used the CSX beamline to image some magnetic domains in an iron-based "antiferromagnetic" material. The ability to image these domains is key to developing spintronics, or spin electronics, for practical applications.

    A schematic of the experimental setup. Coherent x-rays are directed through a pinhole onto the sample, and a detector captures the intensity of light as it is reflected off the sample. The intensity of the signal is reduced near the domain boundaries. On the basis of this "interference," scientists can determine where the boundaries are arranged in space.
  • Images of the antiphase domain boundaries (black wavy lines) after the sample was cooled from above a certain temperature. Images (a) through (d) refer to various thermal cycles providing different magnetic domain and wall configurations each time. The blue arrows indicate the position of a stationary structural defect, used as a reference point.
