Abstract

In this review, the classification of magnetoresistance effects, the electrical conduction mechanisms without and with magnetic field, and the spintronics are briefly summarized. The magnetoresistance effect in the molecular systems including small organic molecules, carbon nanotubes, graphene, conductive polymers and their nanocomposites is critically reviewed. The four normally used models are elaborated to disclose the mechanisms of organic magnetoresistance (OMAR) in the organic systems. The most current applications of these molecular systems are also summarized. These molecular systems are envisioned to create next-generation spintronic and electronic devices for flexible applications.

摘要

在这篇综述中，简要总结了磁阻效应的分类、无磁场和有磁场时的电导机制以及自旋电子学。综述了包括小分子、碳纳米管、石墨烯、导电聚合物及其纳米复合材料在内的分子体系中的磁阻效应。详细阐述了通常使用的四个模型，以揭示有机体系中有机磁阻（OMAR）的机制。还总结了这些分子体系的最新应用。这些分子体系有望为灵活应用创造下一代自旋电子学和电子设备。
