Based on the non-equilibrium Green’s method and density functional theory, the magnetic transport of Fephthalocyanine dimers with two armchair single-walled carbon nanotube electrodes is investigated. The results show that the system can present high-performance spin filtering, magnetoresistance, and low-bias spin negative differential resistance effects by tuning the external magnetic field. These results show that the Fe-phthalocyanine dimer has the potential to design future molecular spintronic devices.
