Sample schematic and experimental details of the STXM-XMCD measurement.
(a) The sample consists of elliptically-shaped magnetic Py elements (red) below a current-carrying stripline. The sample is aligned at 60° with respect to the X-ray beam. The current pulse I(t) through the stripline consists of a 2 ns square pulse superimposed on a 4 ns microwave signal (at 1.8 GHz), as shown in (b). The inset in (b) shows a STXM-XMCD differential image of the Py element, along with the relative directions of the pulse and microwave magnetic fields. (c–h) Time-resolved images of the reversal process in a 4 × 0.4 μm2 Py element.
