(a) Setup of the XMCD measurements at the Co and Eu edges. (b) TEY XA spectrum of the Co and edge with parallel (solid line) and antiparallel (open symbols) orientation of photon spin and magnetization, as measured in remanence. TEY current is normalized by the photocurrent of a reference diode . (c) Asymmetry signal.

XMCD measurements in remanence at the Eu and edge. (a) XA spectrum (only parallel orientation plotted), vertical line at marks XA peak. (b) Gaussian smooth and (c) raw asymmetry data of six scans averaged, all at . (d) XA spectrum (parallel orientation), (e) Gaussian smooth , and (f) raw asymmetry data of four scans averaged, all at .
