Schematic of investigated single-molecule junctions consisting of two serially connected TM(DBTAA) (TM = Fe, Co) molecules embedded between two (4,4) SWCNT electrodes by CACs. The left and right electrodes are indicated by red and blue rectangles, respectively. P (AP) represents parallel-spin (antiparallel-spin) polarization of TM atoms under some external stimulations (e.g., magnetic field).
