Dataset presented in the publication in Applied Physics Letters 119, "The role of spin-lattice coupling for ultrafast changes of the magnetic order in rare earth metals" (2021). Files are in .txt format. Raw data of time- and spin-resolved spectra measured on Gadolinium and Terbium surface states at different pump-probe delays are provided. In the data file, E_B = E- E_F represents the binding energy of the surface state of Tb and Gd. Spin polarization is normalized. Spin, energy, and time-resolved photoemission data of the Tb and Gd surface state for Tb and Gd (0001) films of 10 nm prepared on W(110) in ultrahigh vacuum by molecular beam epitaxy. Measurements in normal emission with an angular resolution of \pm 2.5 degree. Fig.1 Raw data of spin-resolved spectra (majority and minority spin channel) measured on Gadolinium and Terbium surface states at different pump probe delays (ps) and simulated spectra according to the fit described in the paper. Fig. 2 Dynamics of the spin polarization of Terbium and Gadolinium extracted at fixed binding energy as a function of pump-probe delay and from EDCs at various delay. Fig.3 Raw data for the false color plot: Counts as a function of pump-probe delay and binding energy. The Figure is composed of individually measured EDCs as a function of delay as measured. Fig. 4 Surface state binding energy and electron temperature of Gd and Tb as a function of pump probe delay. Binding energy and electron temperature for Tb have been extracted fitting the raw data of Fig. 3. Data for Gd are as published in B. Andres et al. Phys. Rev. Lett. 115, 207404 (2015).
