Electronic origin of x-ray absorption peak shifts
S. Shallcross, C. v. Korff Schmising, P. Elliott +3
Encoded in the transient x-ray absorption (XAS) and magnetic circular (MCD) response functions resides a wealth of information of the microscopic processes of ultrafast demagnetisa…
Mapping the energy-time landscape of spins with helical X-rays
N. Pontius, J. K. Dewhurst, C. Schuessler-Langeheine +5
Unveiling the key mechanisms that determine optically driven spin dynamics is essential both to probe the fundamental nature of ultrafast light-matter interactions, but also to dri…
Skyrmion Alignment and Pinning Effects in a Disordered Multi-Phase Skyrmion Material Co8Zn8Mn4
M. E. Henderson, M. Bleuel, J. Beare +10
Underlying disorder in skyrmion materials may both inhibit and facilitate skyrmion reorientations and changes in topology. The identification of these disorder-induced topologicall…
Ab-initio study of ultrafast spin dynamics in Gdx(FeCo){1-x} alloys
J. K. Dewhurst, Sam Shallcross, I. E. Radu +3
Using an ultrashort laser pulse we explore {\it ab-initio} the spin dynamics of Gd(FeCo) at femtosecond time scales. Optical excitations are found to drive charge from…
Probing the energy conversion pathways between light, carriers and lattice in real time with attosecond core-level spectroscopy
T. P. H. Sidiropoulos, N. Di Palo, D. E. Rivas +16
Detection of the energy conversion pathways, between photons, charge carriers, and the lattice is of fundamental importance to understand fundamental physics and to advance materia…
Numerical analysis of XMCD sum rules at the -edge: when do they fail?
S. Shallcross, J. K. Dewhurst, P. Elliott +3
In the highly non-equilibrium conditions of laser induced spin dynamics magnetic moments can only be obtained from the spectral information, most commonly from the spectroscopy of…
