Spin Transport Properties of Amine-Ended Single-Molecule Magnetic Junctions

The manipulation of spin transport properties in FM/single molecule/FM junctions has attracted intensive attentions due to their potential applications in molecular spin electronics, where FM denotes the ferromagnetic materials. Recently, the first-principle method with the non-equilibrium Green's function approach has been successfully employed to study the conductance switching properties during the stretching [1] of Au/single molecule/Au junctions, which agree well with the experimental observations [2], and the strain-enhanced spin injection in amine-ended single-molecule magnetic junction. [3] The underlying mechanism can be understood by the hard and soft and acid and bases (HSAB) theory and the novel spinterface effect [4]. The former domains the stability of bond between atoms; the latter shows how interface geometry affect the spin properties in this motif.
