Spin Transport in Nanowires

M. Tian, J. Wang, D. Rench, J. Cardellino, P. Schiffer, T. Mallouk, M. Chan and N. Samarth - Penn State University
The interplay between spin transport and exchange coupling profoundly affects charge transport between conventional metals and ferromagnets. This results in  giant magnetoresistance and the spin valve effect in multilayer thin films, phenomena of great importance for magnetic data storage. MRSEC researchers have developed Co-Cu-Co multilayer nanowires to explore these phenomena in nanowire geometries.

Discover Magazine Names NYU Physics Finding One of Top Stories of 2009

The NYU team, led by Jasna Brujic, an assistant professor in NYU’s Department of Physics, developed an innovative way to tabulate the number of spheres-they created a method for determining how spheres pack from inside the jar, making it easier to more accurately count them.

Enhanced Exciton Diffusion using Phosphor Sensitization

Russell Holmes
Graduate student Wade Luhman has demonstrated a route to enhance the short exciton diffusion length (LD) of organic semiconductors by combining fluorescent and phosphorescent materials into a single electron donating thin film.
