Coherent spin-dependent electronic transport is investigated in a molecular junction made of organic molecule (linear chain of benzene rings) attached to two the semi-infinite ferromagnetic (FM) electrodes with finite cross sections (Fig. 1). The work is based on the tight-binding Hamiltonian model and within the framework of a non-equilibrium Green’s function (NEGF) technique. It is shown that tunnel magnetoresistance (TMR) of molecular junction can be large (over 60 %) by adjusting the related parameters, and depends on: (i) the applied voltages and (ii) the number of benzene rings.
