Resonant x-ray scattering study on multiferroic BiMnO3
C. -H. Yang, J. Koo, C. Song +3
Resonant x-ray scattering is performed near the Mn K-absorption edge for an epitaxial thin film of BiMnO3. The azimuthal angle dependence of the resonant (003) peak (in monoclinic…
Fluorescent contacts measure the coordination number and entropy of a 3D jammed emulsion packing
J. Brujic, G. Marty, C. Song +2
Jammed matter is by definition impenetrable to light, rendering the characterization of the 3D geometry difficult. Confocal microscopy of a dyed, refractive index matched emulsion…
Microwave response of vortices in superconducting thin films of Re and Al
C. Song, T. W. Heitmann, M. P. DeFeo +5
Vortices in superconductors driven at microwave frequencies exhibit a response related to the interplay between the vortex viscosity, pinning strength, and flux creep effects. At t…
Terahertz spin currents and inverse spin Hall effect in thin-film heterostructures containing complex magnetic compounds
T. Seifert, U. Martens, S. Günther +20
Terahertz emission spectroscopy of ultrathin multilayers of magnetic and heavy metals has recently attracted much interest. This method not only provides fundamental insights into…
Search for Correlations between HiRes Stereo Events and Active Galactic Nuclei
R. U. Abbasi, T. Abu-Zayyad, M. Allen +61
We have searched for correlations between the pointing directions of ultrahigh energy cosmic rays observed by the High Resolution Fly's Eye experiment and Active Galactic Nuclei (A…
Scaling of fluctuations in a colloidal glass
P. Wang, C. Song, H. A. Makse
We report experimental measurements of particle dynamics in a colloidal glass in order to understand the dynamical heterogeneities associated with the cooperative motion of the par…
