Abstract
We report strong magnetic linear dichroism at the Fe edge of the antiferromagnet (hematite). The relative difference in absorption for light polarized parallel and perpendicular to the magnetic moment is as high as 40% at the Fe edge. The spectra are in excellent agreement with calculations of magnetic dichroism for (3). The magnetic origin of this dichroism is demonstrated by the Morin transition at ≊-10 °C, where the moments in rotate by 90°. Magnetic linear dichroism may be applied to measure the spin orientation in thin films and multilayers, and to image magnetic domains.
