Soft-x-ray magnetic circular dichroism is used as an element-specific magnetometer to determine the magnetic behavior of a buried 4.3 monolayer Mn film in a Fe₂₅Co₇₅/Mn/Fe₂₅Co₇₅ trilayer, which exhibits a 90° coupling between the two ferromagnetic films. By measuring element-specific magnetic hysteresis curves for Fe, Co, and Mn along directions parallel and perpendicular to an applied magnetic field, the magnetization behavior of each element is described, indicating an anomalous in-plane canting of the net Mn moment with respect to the Fe and Co moments by 23°.
