我们利用连续波和脉冲电检测磁共振（cw-EDMR/p-EDMR）研究了有机器件 ITO/ZnPc/Al。样品的共振微波吸收导致电流变化，这可以通过局域自旋载流子的自旋相关复合理论来解释。微波脉冲期间的相干自旋运动显示出两个频率分量，这可归因于具有大和小拉莫尔间隔的自旋对。当考虑自旋对伙伴之间的交换耦合时，CW-EDMR 谱的分析支持了这一点。 （© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
We investigated the organic device ITO/ZnPc/Al with continuous wave and pulsed electrically detected magnetic resonance (cw‐EDMR/p‐EDMR). Resonant microwave absorption of the sample leads to current changes that can be explained by the theory of spin dependent recombination of localized spin carriers. The coherent spin motion during the microwave pulse shows two frequency components, which can be attributed to spin pairs with large and small Larmor separation. This is supported by the analysis of the cw‐EDMR spectrum, when taking into account exchange coupling between the spin pair partners. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
