Ultrafast Magnetic Spectroscopy, Scattering and Full-Field Imaging Using Tabletop High Harmonic Sources*

The observation and manipulation of spin dynamics on the nanoscale is a crucial ability in our quest to engineer quantum materials. We present spectroscopy, scattering, and full field imaging of magnetic nanostructures using EUV high harmonic sources. Our control of EUV polarization, spin and orbital angular momentum, along with high spatial and temporal coherence, allows us to uniquely control and probe spin dynamics on few-femtosecond timescales on up.
