We theoretically investigate the orbital hybridization and spin-dependent transport in organic ferromagnetic co-oligomer molecules. The results reveal that the hybridized orbitals are sensitive to the spin configuration of the two moieties, which manifests in both the eigenvalue and spatial localization. A large tunneling magnetoresistance effect is achieved by calculating the transport property at different spin configurations. This work indicates a magnetic manipulation of molecular conductance, which is expected to be useful in the design of intrinsic organic spin valves.
