32. By taking into account the correct matrix elements in the scattering process, angular momentum conservation is fulfilled. We assume that the possibility to couple to a phonon in such a scattering event is always given, mediated by spin-orbit interaction somehow (e.g., the dispersion of two transverse polarized branches along high-symmetry directions are equal, which allows to form a circularly polarized phonon branch). Quantitative calculations are currently performed by M. Fähnle and his group and not available yet.

46. For long time scales the at 20 ps the temperature of the magnetic system T s is determined from the Langevin function by the decrease in magnetization. For this delay time the electron temperature is set to T e = T s. At negative delay T e and T s are assumed to be at room temperature again which is fulfilled in good approximation and we set T e = T s = 300 K. By this procedure the deposited energy per pulse P (t) within the 15 nm Ni layer can be adjusted. See also supplementary materials section.
