    Local aging phenomena close to magnetic surfaces 

    Baumann, F.; Pleimling, Michel J. (American Physical Society, 2007-09)
    Surface aging phenomena are discussed for semi-infinite systems prepared in a fully disordered initial state and then quenched to or below the critical point. In addition to solving exactly the semi-infinite Ising model ...

    Probing equilibrium by nonequilibrium dynamics: Aging in Co/Cr superlattices 

    Mukherjee, T.; Pleimling, Michel J.; Binek, C. (American Physical Society, 2010-10)
    Magnetization relaxation is investigated in a structurally ordered magnetic Co/Cr superlattice. Tailored nanoscale periodicity creates mesoscopic spatial magnetic correlations with slow relaxation dynamics when quenching ...

    Aging in coarsening diluted ferromagnets 

    Park, H.; Pleimling, Michel J. (American Physical Society, 2010-10)
    We comprehensively study nonequilibrium relaxation and aging processes in the two-dimensional randomsite Ising model through numerical simulations. We discuss the dynamical correlation length as well as scaling functions ...

    Superuniversality in phase-ordering disordered ferromagnets 

    Henkel, M.; Pleimling, Michel J. (American Physical Society, 2008-12)
    The phase-ordering kinetics of the ferromagnetic two-dimensional Ising model with uniform bond disorder is investigated by intensive Monte Carlo simulations. Simple aging behavior is observed in the single-time correlator ...

    Raman-scattering and optical studies of argon-etched GaAs surfaces 

    Feng, G. F.; Zallen, Richard H.; Epp, June Miriam; Dillard, John G. (American Physical Society, 1991-04)
    We have studied the structual damage in low-energy argon-ion-bombarded (ion-etched) GaAs using Raman scattering and ultraviolet reflectivity. When combined with post-bombardment sequential chemical etching, the Raman results ...

    Spectral momentum density of graphite from (e,2e) spectroscopy: Comparison with first-principles calculation 

    Gao, C.; Ritter, Alfred L.; Dennison, John Robert; Holzwarth, N. A. W. (American Physical Society, 1988-03)
    We have measured the spectral momentum density ρ(E,q) of graphite by (e,2e) spectroscopy for momentum parallel and perpendicular to the crystal c axis. In the independent-electron approximation, ρ(E,q)=ΣG‖Uk(G)‖2 ...

    Solving the Ginzburg-Landau equations by finite-element methods 

    Du, Q.; Gunzburger, Max D.; Peterson, Janet S. (American Physical Society, 1992-10)
    We consider finite-element methods for the approximation of solutions of the Ginzburg-Landau equations of superconductivity. The methods are based on a discretization of the Euler-Lagrange equations resulting from the ...

    Transmission-electron spin resonance in dilute CuFe alloys 

    Ritter, Alfred L.; Silsbee, R. H. (American Physical Society, 1978-04)
    Alloys of Cu with nominally 5- and 10-at. ppm Fe were studied by transmission-electron spin resonance (TESR) in the temperature range 2-40 K. The samples were strained in order to remove background signals which hamper ...

    Electron-energy-loss and optical-transmittance investigation of Bi2Sr2CaCu2O8 

    Wang, Y. Y.; Feng, G. F.; Ritter, Alfred L. (American Physical Society, 1990-07)
    The energy-loss function Im(-1/ε) of Bi2Sr2CaCu2O8 has been measured over the range Eloss=0.8 to 80 eV by transmission electron-energy-loss spectroscopy (EELS) (nonimaging). The energy and momentum resolution were 0.1 eV ...

    Optical excitations in Bi2Sr2CuO6 and Bi2Sr2CaCu2O8: Evidence for localized (excitonic) and delocalized charge-transfer gaps 

    Wang, Y. Y.; Ritter, Alfred L. (American Physical Society, 1991-01)
    The optical properties of Bi2Sr2CuO6 (2:2:0:1) and Bi2Sr2CaCu2O8 (2:2:1:2) have been investigated by transmission electron-energy-loss spectroscopy. At low energy, E(loss) less-than-or-equal-to 10.0 eV, common features are ...
