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.
