Abstract Submitted to the    NANOTUBE'04 Conference:

Motivated by the possibility of combining spintronics with molecular structures, we investigate the conditions for the appearence of spin polarization in low-dimensional tubular systems by contacting them to a magnetic substrate. We derive a set of general expressions describing the charge transfer between the tube and the substrate and the relative energy costs. Using a tight-binding model for the electronic structure we are able to estimate the magnitude and stability of the induced moment. This indicates that sizeable magnetic moments can be induced in carbon nanotubes.
