Figure 12
Magnetic domain patterns from XMCD measurements in a Pt /Co multilayer sample with an out-of-plane magnetic moment. Images were taken at the remanent state after applying out-of-plane magnetic fields of 0 mT (left), 25 mT (middle) and 72 mT (right). The images were taken with a photon energy of 780 eV (L3 peak in the Co XAS spectrum) and a kinetic energy of 1.6 eV. The undulator phase +(−)16 mm is used for the right (left) circular polarization. The scale bar is 1 µm. |
