Scientific Achievement
Time-resolved x-ray nanodiffraction reveals new transition pathways during an ultrafast phase transition that are fundamentally different from quasi-equilibrium transitions.
Significance and Impact
Crucial nanoscopic insights into ultrafast phase transitions obtained via spatiotemporally-resolved structural characterization provide opportunities for controlling nanoscale phases on ultrafast time scales.
Research Details
- A first-of-its-kind laser-pumped x-ray nanodiffraction imaging capability with 25 nm and 100 ps resolutions at the Advanced Photon Source was utilized.
- Key nanoscale processes were discovered in the optically-induced phase transition of FeRh.
