碳纳米管(CNT)是最有希望在不久的将来给传统电子学带来革命性变化的新材料。当碳纳米管夹在铁磁电极之间时，它的行为就像传统自旋阀中的隔离物，经常导致相当大的巨磁电阻效应(GMR)。本文对碳纳米管中有关电子关联的一些问题进行了综述。然而，主要关注的是对通过纳米管的电子传输至关重要的下列效应：(1)纳米管/电极耦合和(2)管间相互作用。结果表明，这些效应可能解释了最近一些关于巨磁电阻的实验报告，包括那些关于负(反)巨磁电阻的实验报告。(2015Wiley-VCH Verlag GmbH&Co.KGaA，Weinheim)
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)
