Author(s): A. Goris, K. M. Döbrich, I. Panzer, A. B. Schmidt, M. Donath, and M. Weinelt The spin-dependent lifetimes of hot electrons in fcc Co films were studied by spin- and time-resolved two-photon photoemission. Even for excitation energies close to the Fermi level, we find almost identical lifetimes for majority and minority electrons. This result contradicts ab initio theories pr... [Phys. Rev.
