FIG. 1.

(Color online) Schematic of thermally driven electric currents for an SMM tunnel junction and reversal of the SMM’s spin. The carrier of heat current is the hole for the LUMO level below (a) and the electron for above (b), both of them leading to opposite orientations of the SMM’s core spin.

FIG. 2.

(Color online) The SMM’s magnetization as a function of bias temperature at gate voltages  = −1.5 meV (black line, solid symbol) and  = +1.5 meV (red line, open symbol) with  = 0, and  = 0.1 meV for different polarizations and equilibrium temperatures.

(Color online) The SMM’s magnetization vs loops for  = 0.2, 0.6, and 1.0 meV with  = 25 meV fixed.

FIG. 4.

(Color online) (open circles) and (solid triangles) as functions of (the magnetic quantum number of the SMM’s state) with  = 10,  = 0.1 meV, and  = 0.06 meV. |1, − − 1/2〉 is the lowest energy state (a), (b), |0, 〉 is the lowest energy state (c), and (d).
