Abstract

Spin-dependent transport through a family of biphenyl-dithiolate molecules was investigated theoretically. Torsion angles φ between the two phenyl rings in these molecules can be chemically tuned. Calculated conductances of molecular junctions are proportional to cos²φ, but their magnetoresistances are nearly independent on φ. Calculation results indicate that resistances and magnetoresistances of molecular junctions can be engineered separately.
