Research Highlights
Time-resolved Kerr reflectometry (TRKR) is used to investigate the long-range transport of spins by surface acoustic waves in undoped GaAs (110) quantum wells. TRKR measurements under an applied magnetic field demonstrate the coherent precession of the optically generated electron spin during acoustic transport over several micrometers and yield information about the relaxation processes for moving spins.
Imaging ellipsometry is a powerful tool to detect and characterize graphene on any flat substrate. Variable angle spectroscopic ellipsometry is used to explore the dispersion of the optical constants of graphene in the visible range with high lateral resolution. In this way, the influence of the substrate on graphene’s optical properties can be investigated.
Ultrathin cobalt-based multilayer films were deposited by sputtering. A large perpendicular magnetic anisotropy and an ideal square out-of-plane hysteresis loop were attained even for ultrathin superlattice films with a total thickness of 1.2-2.4 nm. The use of these films will enable the development of gigabit-scale nonvolatile memory. Keep up-to-date with all the latest news and articles in APL

Applied Physics Letters will be represented at AIP Publishing booth #400 at the APS March Meeting, 21 – 25 March. You also can meet some of APL's editors at the joint AIP/APS Meet the Editors Reception on Tuesday, 22 March at 4:00 p.m.in the Dallas Convention Center, Lobby E. When you visit the AIP Publishing booth you can enter to win an iPad and discover the latest news about APL and other AIP journals.

Still Need a Calendar? The Emilio Segrè Visual Archives (ESVA) has produced a beautiful 2011 calendar in two sizes featuring some of the most interesting photos from our collection. The calendar shows physicists as you've never seen them before and all proceeds benefit the Emilio Segrè Visual Archives.
