We theoretically investigate the orbital hybridization and spin-dependent transport in organic ferromagnetic co-oligomer molecules. The results reveal that the hybridized orbitals are sensitive to the spin configuration of the two moieties, which manifests in both the eigenvalue and spatial localization. A large tunneling magnetoresistance effect is achieved by calculating the transport property at different spin configurations. This work indicates a magnetic manipulation of molecular conductance, which is expected to be useful in the design of intrinsic organic spin valves.

有机铁磁共聚体的轨道杂交和磁阻的磁操纵

我们理论上研究有机铁磁共聚分子中的轨道杂交和自旋依赖性运输。结果表明，杂化的轨道对两个部分的自旋构型敏感，这表现在特征值和空间定位上。通过计算不同自旋构型下的输运性能，可实现较大的隧穿磁阻效应。这项工作表明了对分子电导的电磁操纵，这有望用于本征有机自旋阀的设计。
