Figure 8.
Experimental setup for fluorescence-yield depth-resolved X-ray absorption (XAS) and X-ray magnetic circular dichroism (XMCD). Fluorescence X-ray emitted after XAS was acquired separately at different detection angles θd with a charge-coupled device. Lowest θd was determined to be ∼0.1°. Magnetic field was tilted by rotations θi and θis of 90° and 30°, respectively, implying that magnetic field of 0.87 T was applied in the out-of-plane direction and rotated 30° from the in-plane direction.
