A magnetization vector M imaging using a transmission x-ray microscope with magnetic circular dichroism (MCD) contrast is demonstrated. MCD images through a semitransparent, 33-nm-thick Fe film are measured at the Fe L-3 edge along three different x-ray propagation directions to determine all three components of the M. The transmission images clearly display the vector nature of complex microstructures, associated with the M reversal between oppositely oriented 180 degrees domains, including not only 90 degrees domains, a Neel wall-like structure, and an extended ripple structure, but also a striking feature of localized magnetization spirals with perpendicular components at their cores. These studies have important implications for applications of this technique to better understand the expected features as well as details of domain-wall structures.
