A possibility to manipulate the magnetic and polarizability characteristics of systems containing mobile electrons by means of external fields opens new perspectives for molecular electronics. From this point of view mixed valence clusters d¹–d³ with two-electron transfer are a challenging subject, since under the action of the constant external electric field, it is possible not only to manipulate with the spin of the ground state of the cluster and, consequently, with its magnetic properties but also to produce a pronounced significant polarizability due to the suppression of the two-electron tunneling by this field. The intracluster Heisenberg exchange interaction, the difference in Coulomb interaction for possible cluster configurations, and the coupling with an external electric field are taken into consideration in the model, which predicts spin transitions that are induced by this field and accompanied by appreciable changes in the magnetic properties and polarizability.

电场对两电子转移团簇的磁性和极化性质的影响

通过外部场控制包含移动电子的系统的磁和极化特性的可能性为分子电子学打开了新的视野。从这个角度来看，混合价簇d ¹ –d ³具有双电子转移是一个具有挑战性的课题，因为在恒定的外部电场的作用下，不仅可以利用团簇的基态的自旋来操纵，因此还可以利用其磁性能来制造原子团。由于该场抑制了双电子隧穿，因此具有显着的显着极化率。模型中考虑了团簇内海森堡交换相互作用，库仑相互作用的差异以及可能的簇构型，以及与外部电场的耦合，该模型预测了由该场引起的自旋跃迁，并伴随着磁场的明显变化性质和极化率。
