Time-Resolved Scanning Transmission X-ray Microscopy (TR-STXM) is a powerful element-specific spectromicroscopy tool to study dynamic magnetic processes for such as spintronics and magnonics applications. It provides sub-50 nm spatial resolution and picosecond, phase-resolved time sampling. In this presentation, I will introduce the TR-STXM technique, and describe the setup developed at the Advanced Light Source at Berkeley Lab [1]. TR-STXM on samples ranging from Py/Co microstructures [2], to magnetosomes [3,4] will be shown together with supplementing ferromagnetic resonance spectroscopy and micromagnetic simulations. The talk will be concluded with an outlook on Time-Resolved X-ray ptychography.
