摘要: Based on density functional theory and non-equilibrium Green’s function formalism, we explore the effect of Fe atom in Au-Fe@C20-Au monomer dimer systems comparison with C20 fullerene molecular junctions. We calculate spin-dependent transmission coefficient, spin polarization also their thermoelectric coefficients to investigate magnetic properties system. Our results indicate that presence atoms enhances substantially spin-filter increases figure merit suggest Au-(Fe@C20)2-Au system is a suitable junction for designing spin-filtering devices eventually it good candidate spintronic applications.
