Spin-polarized current and tunneling magnetoresistance (TMR) are studied for two lengths of phenyl based molecules using Green's function formalism. The HÃ¼ckel method is used for describing the Hamiltonian of the molecules. Our results show that an increase in length of the BPDT molecule leads to an increase in the spin-polarized current and a decrease in the TMR at higher voltages.
