X-ray Magnetic Circular Dichroism (XMCD) spectra from a 5 μm polycrystalline Gd foil were measured in transmission across the Gd L2,3 edges using the Multipurpose Unit for Synchronisation, Sequencing and Triggering (MUSST) card developed at the European Synchrotron Radiation Facility (ESRF). The circularly polarized x-rays were produced by a diamond phase-plate and their helicity was rapidly reversed through the use of a piezo driven device. The signal measured for each helicity was recorded by the MUSST card synchronized to the helicity reversal. The results are compared to those obtained using an analogue lock-in technique.

    We present a study of exchange bias in ferromagnet/antiferromagnet/ferromagnet (FM/AFM/FM) trilayers, with in-plane and out-plane easy axes. Using element-specific x-ray magnetic circular dichroism, we demonstrate that simultaneous in-plane and out-of-plane exchange bias can be induced using a...
