Abstract
On the basis of systematic density functional theory calculations, we investigate the electrical and spintronic multifunctional switch through the control of transverse external electrical field (EEF) on a one-dimensional bimetallic sandwich molecular wire, (CpFeCpV)∞. The wire shows robust ferromagnetism under applied EEFs of up to 1.0 V/ Å. By switching the EEF on and off at 1.0 eV/ Å, the molecular wire can be converted between semiconducting and half-metallic states, and it is also possible to change its magnetization direction simultaneously. This finding opens up the potential applications of one-dimensional bimetallic sandwich molecular wire as spintronic materials.
