Spin-polarized conduction in a photoswitching dithienylethene molecule attached to Ni leads
(English)Article in journal (Other academic) Submitted
The finite-bias conduction properties of the photoswitching dithienyle the molecule attached to spin-polarized nickel electrodes are investigated. We find that the ratio of conduction between the open and closed isomers is around 60 at low bias, decreasing to 50 at a bias of 1 V. The I ¡ Vcharacteristics for the spin up and spin down channels are very similar, despite the fact that the Ni electrode density of states is very different for the two cases - Ni is known to be a so-called strong ferromagnet meaning that it is almost completely spin polarized at the Fermi level.
