Ultrafast charge and spin dynamics in ferromagnets
CLEO: QELS Fundamental Sciencepp FF1C.2 /1-2 , ISBN 978-1-943580-76-7 (2020)
With our experiment we demonstrate all-optical control of magnetization in a ferromagnet with an unprecedented sub-femtosecond time resolution. The reported results open the doors to a new generation of spintronic devices with petahertz clock-rates.
