In this work we combine theory and experiment to study transient magnetic circular dichroism (TRMCD) in the extreme ultraviolet spectral range in bulk Co and CoPt. We use the ab initio method of real-time time-dependent density functional theory to simulate the magnetization dynamics in the presence of short laser pulses. From this we demonstrate how TRMCD may be calculated using an approximation to the excited-state linear response. We apply this approximation to Co and CoPt and show… Expand

Ultrafast laser induced local magnetization dynamics in Heusler compounds
This work shows that more complex magnetic materials - using the example of the Heusler and half-Heusler alloys - allow for purely optical excitations to cause a significant change in the local moments on the order of 5 fs, and demonstrates that qualitative behaviour of this rich magnetic response to laser light can be deduced from the ground-state spectrum.
