In this work, using a tight-binding Hamiltonian and a non-equilibrium Green's function technique, the spin-dependent transport properties of the electrode/ single molecule/electrode system is numerically investigated. We choose a typical ferromagnetic (FM) metal with simple cubic structure as the electrode and polyacene as the molecule. Based on Landauer Formalism, we determined the current-voltage (I-V) characteristic of the system. In addition, the tunnel magnetoresistance (TMR) of the FM/polyacene/FM structure is calculated. Applying the gate voltage on the polyacene molecule modified the I-V and TMR curves.
