Spin transport in carbon-based materials has stimulated much interest due to their ballistic conductance and a long phase coherence length. While much research has been conducted on individual carbon nanotubes, current growth and placement techniques are incompatible with large-scale fabrication. Here, we report on nonlocal spin injection and detection in single-walled carbon nanotube networks. We observe spin transport over a distance of 1 μm and extract a spin diffusion length of 1.6-2.4 μm with an injected spin polarization from CoFe into nanotube network of 18%-41%. Our observations demonstrate that spin transport is possible in carbon nanotube networks due to the formation of natural tunnel barriers between nanotubes and metallic contacts. © 2012 American Physical Society.
