Abstract

We report on the giant magnetoresistance (GMR) of multiwall carbon nanotubes with ultrasmall diameters. In particular, we consider the effect of the interwall interactions and the lead/nanotube coupling. Comparative studies have been performed to show that in the case when all walls are well coupled to the electrodes, the so-called inverse GMR can appear. The tendency towards a negative GMR ...
