Ultrafast magnetic spectroscopy using tabletop high harmonic sources

The measurement and control of nanoscale spin dynamics is essential for the understanding and development of quantum materials. We present a new instrument along with precise spectroscopic measurements of ultrafast magnetic phenomena using extreme ultraviolet high harmonic sources. Our unique instrument allows us to optically control and probe spin dynamics of complex magnetic materials with element specificity on few-femtosecond timescales on up.
