Abstract
We study electron spin transport through carbon nanotubes contacted by ferromagneticelectrodes. The resistance of a ferromagnetically contacted multiwalled nanotube switches hysteretically as a function of applied magnetic field, with a maximum resistance change of 9% at 4.2 K. Magnetoresistance measurements of carbon nanotubes having one cobalt contact and one platinum/gold contact, however, show no switching. In addition, we present calculations of the magnetoresistance ratio for the ferromagneticnanotube device, and predict that a resistance change of 25% is possible.This publication has 14 references indexed in Scilit:
