Abstract

Giant magnetoresistance (GMR) through a single phthalocyanine molecule (H2Pc) was studied by means of a spin-polarized scanning tunneling microscopy (STM) technique. Spin-polarized STM shows surface electronic spin and quantum structures of nano materials, such as single atoms, single molecules, nano-clusters, with an atomic resolution. Single molecular magnetic junction was fabricated by contacting a ferromagnetic STM tip to a single molecule adsorbed on nano magnets. We measured GMR of +60% and -50% through [Co/H2Pc/Co(111)] and [Fe/H2Pc/Mn(001)] junctions, respectively, in ultra-high vacuum at 4.6K. Single organic molecules can be a new material for spintronics.
