Charge and Spin Currents in Ferromagnet-Insulator-Superconductor Tunneling Junctions Using Hg-1223 High- Superconductor
Figure 6
The , , , , and atomic orbital parts of the spin currents drawn in Figures 5(d), 5(e), and 5(f). As orbitals, the Cu orbitals of Cu2 atom shown in Figure 1 have been selected. (a), (b), and (c) of the present figure correspond to Figures 5(d), 5(e), and 5(f), respectively. Present figure clearly shows that the most dominant spin current is observed in an electron tunneling between orbits of ferromagnetic iron and Cu orbit of Hg- high- superconductor.
