State-resolved ultrafast charge and spin dynamics in [Co/Pd] multilayers
Loïc Le Guyader, Daniel J. Higley, Matteo Pancaldi +17
We use transient absorption spectroscopy with circularly polarized x-rays to detect laser-excited hole states below the Fermi level and compare their dynamics with that of unoccupi…
Tracking the Ultrafast Non-Equilibrium Energy Flow between Electronic and Lattice Degrees of Freedom in Crystalline Nickel
P. Maldonado, T. Chase, A. H. Reid +9
Femtosecond laser excitation of solid-state systems creates non-equilibrium hot electrons that cool down by transferring their energy to other degrees of freedom and ultimately to…
Distinguishing Local and non-Local Demagnetization in Ferromagnetic FePt Nanoparticles
Patrick W. Granitzka, Alexander H. Reid, Jerome Hurst +21
Time-resolved coherent X-ray diffraction is used to measure the spatially resolved magnetization structure within FePt nanoparticles during laser-induced ultrafast demagnetization.…
Ultrafast X-Ray Induced Changes of the Electronic and Magnetic Response of Solids Due to Valence Electron Redistribution
Daniel J. Higley, Alex H. Reid, Zhao Chen +13
We report a novel mechanism, consisting of redistribution of valence electrons near the Fermi level, during interactions of intense femtosecond X-ray pulses with a Co/Pd multilayer…
Spin-current-mediated rapid magnon localisation and coalescence after ultrafast optical pumping of ferrimagnetic alloys
E. Iacocca, T-M. Liu, A. H. Reid +31
Sub-picosecond magnetisation manipulation via femtosecond optical pumping has attracted wide attention ever since its original discovery in 1996. However, the spatial evolution of…
Triply degenerate nodal points in RERhGe (RE=Y, La, Lu)
Peng-Jie Guo, Huan-Cheng Yang, Kai Liu +1
As a new type of fermions without counterpart in high energy physics, triply degenerate fermions show exotic physical properties, which are represented by triply degenerate nodal p…
