摘要：

We report the operation of spin-valve structures formed from arrays of aligned carbon nanotubes. The devices require only one deposited ferromagnetic layer with the embedded iron catalyst nanoparticle serving as the other magnetic electrode. A peak in the resistance occurs clearly as a result of the reversal of the magnetization of the electrodes. Device magnetoresistance ratios reach 25%, yielding an estimate of the spin scattering length of 9 mu m at low temperature. (c) 2008 American Institute of Physics. [DOI: 10.1063/1.2999374]
