Electron Dynamics in Spin System
The spin relaxation time of electrons controls the spin accumulation in ferromagnetic/nonmagnetic junctions, the current driven motion of domain walls in nanowires, the demagnetization time in laser-driven demagnetization experiments, and the life time of a spin population after optical pumping. Time-resolved X-ray dichroism techniques offer new ways of detecting spin dynamics and understanding the underlying physics. Because of their element specificity, the sensitivity to spin and orbital magnetization, and the possibility to reach nanometer spatial resolution, these techniques are particularly suited for the study of complex materials, multilayers, nanostructures, junctions, and multicritical systems with coupled spin, orbital, electric, and charge orders. This workshop aims at identifying the new science that can be addressed using next-generation ultrafast x-ray sources and x-ray detectors.
