    • The general form of the SMC contains G r and G t , where G t = S - 1 mn t mn t mn and t mn () is the transmission matrix for u(down) electrons. However, in metallic junctions, G t sharply decreases to zero with the thickness of magnetic layers, and thus, G t can be safely neglected for thicker junctions.

    • We have checked the effect of the lattice constant mismatch for Pt and Py by using the lateral supercell sizes of Pt (9 9) and Py (10 10), and found that the real part of SMC generally decreases at most about 10. However, the main conclusions in this paper are unaffected.

    • We have checked the lateral supercell size (N) dependence on the SMC uto N 14 14, and found that the SMC is already converged for N 6 6. Therefore, we have adopted N 6 6 for calculations of the SMC presented here.
