Ultrafast Magnetic Spectroscopy and Scattering Using Tabletop High Harmonic Sources

ORAL

Abstract

The measurement and control of nanoscale spin dynamics is essential for the understanding and development of quantum materials. We present spectroscopy and scattering measurements of nanomagnetic materials 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. Recent experimental improvements have dramatically reduced the noise of our EUV sources, allowing us to make precise measurements of ultrafast magnetic phenomena.
