Carbon nanotubes (CNT) belong to the most promising new materials which can in the near future revolutionize the conventional electronics. When sandwiched between ferromagnetic electrodes, the CNT behaves like a spacer in conventional spin‐valves, leading quite often to a considerable giant magneto‐resistance effect (GMR). This paper is devoted to reviewing some topics related to electron correlations in CNT. The main attention however is directed to the following effects essential for electron transport through nanotubes: (i) nanotube/electrode coupling and (ii) inter‐tube interactions. It is shown that these effects may account for some recent experimental reports on GMR, including those on negative (inverse) GMR. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
