On Ultrafast Spin Dynamics: Spin Dependent Fast Response of Hot Electrons, of Band--Structure
M. Avignon, K. H. Bennemann
Different energy shifts for majority and minority electrons occur. Thus, for example in case of (laser) excited ferromagnetic metals majority and minority electrons may respond dif…
Model study for the nonequlibrium magnetic domain structure during the growth of nanostructured ultrathin films
R. Brinzanik, P. J. Jensen, K. H. Bennemann
The nonequilibrium magnetic domain structure of growing ultrathin ferromagnetic films with a realistic atomic structure is studied as a function of coverage and temperature. We app…
Nonequilibrium Magnetization Dynamics of Nickel
J. Hohlfeld, E. Matthias, R. Knorren +1
Ultrafast magnetization dynamics of nickel has been studied for different degrees of electronic excitation, using pump-probe second-harmonic generation with 150 fs/800 nm laser pul…
Theory for the Ultrafast Structural Response of optically excited small clusters: Time-dependence of the Ionization Potential
H. O. Jeschke, M. E. Garcia, K. H Bennemann
Combining an electronic theory with molecular dynamics simulations we present results for the ultrafast structural changes in small clusters. We determine the time scale for the ch…
Dynamical Mean Field Theory for Perovskites
P. Lombardo, J. Schmalian, M. Avignon +1
Using the Hubbard Hamiltonian for transition metal-3d and oxygen-2p states with perovskite geometry, we present a dynamical mean field theory which becomes exactin the limit of lar…
Theory for Spin-Polarized Oscillations in Nonlinear Magneto-Optics due to Quantum Well States
T. A. Luce, W. Huebner, K. H. Bennemann
Using an electronic tight-binding theory we calculate the nonlinear magneto-optical response from an x-Cu/1Fe/Cu(001) film as a function of frequency and Cu overlayer thickness (x=…
