Single laser pulse magnetization reversal in rare earth and transition metal-based multilayers !
We recently published in Nature Communication the results obtained thanks to a close collaboration between the Spin Team and the Spintec laboratory. In this study, we demonstrate that single laser-pulse switching of magnetization can be achieved for a wide range of rare earth and transition metal multilayers, making this phenomenon much more general. At high laser intensities, concentric ring domain structures are induced. Alongside the demonstration of an in-plane reorientation of the magnetisation, a precessional reversal mechanism explains all the observed features.
