Strong XMCD-PE\(_{\text {meas}}\) obtained under different polar angles \(\Theta\) at \(T_{\text {low}}\) from (a) a bare \(11\) nm EuO film and (b) an \(11\) nm EuO film with a \(4\) nm Fe overlayer. As expected for the in-plane magnetized sample, for both Eu and Fe, the XMCD-PE\(_{\text {meas}}\) decreases with increasing \(\Theta\).
