Tunable charge and spin Seebeck effects in magnetic molecular junctions

We study the charge and spin Seebeck effects in a spin-1 molecular junction as a function of temperature, applied magnetic field, and magnetic anisotropy (D) using Wilson’s numerical renormalization group. A hard-axis magnetic anisotropy produces a large enhancement of the charge Seebeck coefficient Sc (∼kB/|e|) whose value only depends on the residual… (More)
