Abstract
The power of time-and spin-resolved two photon photoemission is demons trated. This method allows the determination of the spin-dependent dec ay of an excited electron population in ferromagnetic materials by mea ns of a real time experiment. The lifetime of majority-spin electrons is found to be longer compared with that of minority-spin electrons fo r both cobalt and iron. This study shows that the relaxation dynamics of excited electrons is strongly influenced by the imbalance between m ajority-and minority-spin electrons in a ferromagnet.
