ABSTRACT
We presented a theoretical study on the spin-polarized transport of one single-molecule magnet. The results show it has spin filter behavior, and can also be used as a molecular spin valve with large abnormal magnetoresistance, which is an excellent candidate for spintronics of molecular devices. It is also found that the steplike features with negative differential resistance in the I-V curve indeed originate from the discreteness and narrow features in the density of states of the molecular levels.

Such an interaction opens a pathway to the manipulation of electron spins within non-magnetic semiconductors, in the absence...
