In order to obtain a microscopic understanding of ultrafast demagnetization, information on the response of all three subsystems is required. A consistent description of demagnetization and microscopic energy flow, however, is still missing. Here, we combine a femtosecond electron diffraction study of the ultrafast lattice response of nickel to laser excitation with ab initio calculations of the electron-phonon interaction and energy-conserving at","authors_text":"Daniela Zahn, Dieter Engel, Florian Jakobs, H\\'el\\`ene Seiler, Jan Vorberger, Ralph Ernstorfer, Thomas Vasileiadis, Tim A.
