Research Highlights of FY19

FY19_Collage.jpg

Here are the highlights from our 7 publications in fiscal year 2019. This year we explored a range of topics spanning actinide spectroscopy, ionic tuning of magnetism, oxide radiation dynamics, electronic reconstructions, and more! We continue to develop new ways to integrate atomic-scale imaging and spectroscopy with fundamental theory calculations to offer new insight into complex nanoscale materials phenomena.
