Research Abstract |
We have studied the magnetoresitance (MR) of single molecular junctions using Ni electrodes by the mechanically controllable break junction method. When the magnetic field was applied orthogonal to the current path, the MR of Ni/BDT/Ni junction changed more than 30 %, while that of tunnel junction without molecules showed a change of about a few %. The sign and ratio of MR for the tunnel junction was different from those for single molecular junctions, indicating that the coupling between a molecule and electrodes drastically affected to the MR behavior.
