<h3>Abstract:</h3> <h3>Soft X-ray Microscopy - Investigating Materials in Action</h3><h3> </h3><h3>X-ray based spectroscopy and microscopy has been shown to be a powerful tool for the characterization of complex materials on the nanoscale. Using polarization dependent effects (dichroism) we are able to learn about magnetic, structural and electronic order, with tens of nanometer spatial resolution. In addition, so called photon-in, photon-out techniques are insensitive to the presence of external stimuli or even changes in ambient conditions, which allows us to study devices in-operando in state-of-the-art x-ray microscopes. Altogether, these features have led to the development of a strong international user community with a focus on e.g. battery devices or magnetic and electric devices. However, the feature that synchrotrons are pulsed sources of x-rays is typically less used by experimentalists.</h3> <h3>Synchrotrons operate at repetition rates up to 500 Mhz producing x-ray pulses that are less than 100 picosecond long with very little temporal jitter (~10ps). By using point detectors, e.g. Avalanche Photodiodes, and fast electronics with bandwidths of 10 Ghz or more it is then possible to follow reversible processes with about 10 picosecond time resolution.</h3> <h3>In this talk I will describe several examples of how we can use synchrotron radiation to gain insight into materials that are otherwise very difficult or impossible to obtain using lab based methods. I will also describe current efforts to increase sample throughput at synchrotrons, which are typically more geared towards fundamental science than applied technological questions.</h3> <h3>Read more:</h3><a href="https://www.nature.com/articles/s41565-022-01311-0" title="https://www.nature.com/articles/s41565-022-01311-0" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">Three-dimensional topological magnetic monopoles and their interactions in a ferromagnetic meta-lattice - Nature Nanotechnology</a><a href="https://www.nature.com/articles/s41565-022-01311-0" title="https://www.nature.com/articles/s41565-022-01311-0" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">nature.com</a> <a href="https://www.sciencedirect.com/science/article/pii/S1385894724054834" title="https://www.sciencedirect.com/science/article/pii/S1385894724054834" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">Direct evidence from STXM analysis of enhanced oxygen storage capacity in ceria through the addition of Cu and Mg: Correlation of HT-WGS reaction performance</a><a href="https://www.sciencedirect.com/science/article/pii/S1385894724054834" title="https://www.sciencedirect.com/science/article/pii/S1385894724054834" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">sciencedirect.com</a>

<h3>Speaker Bio:</h3> <h3>Dr. Hendrik Ohldag</h3><h3>Staff Scientist Spectromicroscopy, Photon Science Operations</h3><h3>The Advanced Light Source Lawrence Berkeley National Laboratory</h3><h3>IEEE Magnetics Society, IEEE Fellow</h3><h3> </h3><h3>Hendrik Ohldag received the Ph.D. in experimental physics from the Universität Düsseldorf, Germany, in 2002.</h3> <h3>He joined the Stanford Synchrotron Radiation Light Source (SSRL) in 1999 as a research assistant as part of his Ph.D. research. After a postdoctoral fellowship at SSRL he became a permanent member of the research staff in 2005 before he joined the Advanced Light Source (ALS) in Berkeley as a staff member in 2018.</h3> <h3>Dr. Ohldag’s research focuses on using polarized x-rays generated by a synchrotron to study magnetic materials and complex chemical surfaces and interfaces in advanced x-ray microscopes.</h3><h3> </h3><h3>He was awarded the David. A Shirley Award at the ALS in 2006 for “outstanding contribution in using photoemission electron microscopy for the study of magnetic materials” and he was a Distinguished lecturer of the IEEE Magnetics Society in 2017 He has been named a fellow of the American Physical Society, the American Vacuum Society as well as IEEE. He holds adjunct faculty positions at the University of California Santa Cruz and Stanford University.</h3>
