Abstract
We present transport measurements of ferromagnetically contacted carbon nan otubes. The resistance of a ferromagnetically contacted multi-walled nanotu be switches hysteretically as a function of applied magnetic field. with a maximum resistance change of 9% at 4.2 K. Our observed magnetoresistance su ggests that spin polarized current is injected into the carbon nanotube and conduction occurs without randomization of the spin polarization. Backgrou nd details: of the spill transport mechanism are discussed. (C) 2001 Elsevi er Science B.V. All rights reserved.
