    Electron–phonon coupling in 122 Fe pnictides analyzed by femtosecond time-resolved photoemission
    (Milton Park : Taylor & Francis, 2013) Rettig, L.; Cortés, R.; Jeevan, H.S.; Gegenwart, P.; Wolf, T.; Fink, J.; Bovensiepen, U.
    Based on the results from femtosecond time-resolved photoemission, we compare three different methods for the determination of the electron–phonon coupling constant λ in Eu- and Ba-based 122 FeAs compounds. We find good agreement between all three methods, which reveal a small λ < 0.2. This makes simple electron–phonon-mediated superconductivity unlikely in these compounds.
