(a), (b), and (c) on the first line are results calculated for the N/I/S junction; that is, the iron is in nonmagnetic phase, whose DOS is shown in Figure 3(a). (d) to (o) are for the F/I/S junction. (d), (e), and (f) on the second line are results calculated for a ferromagnetic iron with the electron configuration of , whose DOS is shown in Figure 3(b). (g), (h), and (i) on the third line are those for , whose DOS is shown in Figure 3(c), (j), (k), and (l) on the fourth one are for , whose DOS is shown in Figure 3(d), and (m), (n), and (o) on the bottom line are for , whose DOS is shown in 3(e). The - characteristics drawn in (a), (d), (g), (j), and (m) on the left column have been obtained by setting a parameter to , those in (b), (e), (h), (k), and (n) on the middle column are for , and those in (c), (f), (i), (l), and (o) on the right column are for .
