Quantized conductance in an atom-size bridge made from magnetic materials
With the aid of the Hubbard model, and considering orbital degeneracies, we investigate how the magnetic properties of atom-size bridges affect the quantum transport of electrons through them. Within the Hartree–Fock approximation, we calculate the corresponding total energy of the electron system o...

description | With the aid of the Hubbard model, and considering orbital degeneracies, we investigate how the magnetic properties of atom-size bridges affect the quantum transport of electrons through them. Within the Hartree–Fock approximation, we calculate the corresponding total energy of the electron system of the atom-size bridge as it is stretched in length. Our numerical results show that stretching the atom-size bridge induces changes in its magnetic state, from paramagnetic to ferromagnetic, and also vice versa. Furthermore, the corresponding conductance variation of the atom-size bridge is demonstrated. |
