Magnetoresistance in Au/1,4-benzene-dithiol/Au and Au/1,4-benzene-dimethanethiol/Au single-molecule junctions

Positive and negative magnetoresistance (MR) in single-molecule Au/BDT/Au and Au/BDMT/Au junctions appeared at 100 mT, revealing π-orbital influence. Differences in MR behaviors arise from singlet-triplet state modulation by exchange interaction, explaining the MR sign reversal. These findings provide new insight into magneto-transport in π-conjugated molecular junctions.

Abstract

Positive and negative magnetoresistance (MR) in single-molecule Au/BDT/Au and Au/BDMT/Au junctions appeared at 100 mT, revealing π-orbital influence. Differences in MR behaviors arise from singlet-triplet state modulation by exchange interaction, explaining the MR sign reversal. These findings provide new insight into magneto-transport in π-conjugated molecular junctions.
