Abstract
The effect of magnetic STM-tip on electronic, magnetic and electronic transport properties through the molecule junction STM-tip-Co/CoPc/Co(111), has been investigated by mean of ab initio electronic structure calculations. The spin transition has been studied by varying the distance (passing from the tunneling regime to the contact regime) between the tip and the CoPc molecule in both configurations, parallel and anti-parallel. Our calculation shows that the transition of spin of the Co atom of CoPc molecule has led to a change of the sign of the Magneto-Resistance (MR). It is also shown that the characteristic I-V has been influenced by this spin-transition of central atom of CoPc molecule.
