Figure 4: (a) Normalized charge and spin currents, and , defined by (6) and (b) flows of the majority () and minority () spin electrons, and . Those have been calculated as a function of , where is the magnetic moment calculated for Mn atom. The is the normalized voltage applied to the // tunneling junction, which has been set to , that is, mV in real voltage. Note that relations and are held.
