Time-resolved imaging of antiferromagnetic skyrmion interactions

Abstract Quantifying particle interactions is central to understanding and controlling collective dynamics in particle-based devices such as those comprising skyrmion ensembles. Here we directly visualize, in real time, the nanosecond current-driven dynamics of an antiferromagnet...

In situ electron microscopy of LaNiO3 transformation during reduction and methane dry reforming

Abstract By in situ electron microscopy we show the intermediate phase formation during decomposition of LaNiO 3 , a model methane dry reforming (DRM) catalyst, under different gas atmospheres. By combining dark- and bright-field imaging with secondary-electron contrast and opera...
