a, First configuration. I is injected from contacts 1 and 6 and V is measured between contacts 2 and 3. b–e, V–I characteristics (b, d) and dV/dI (c, e) at 80 K and at various magnetic fields B for I⊥B (b, c) and for I‖B (d, e). f, g, Δ(dI/dV)B = (dI/dV)B − (dI/dV)0 T for I⊥B (f) and for I‖B (g). h, Second configuration. V is measured between contacts 4 and 5. i–n, Corresponding characteristics (i, k) and dV/dI (j, l) for I⊥B (i, j) and for I‖B (k, l). m, n, Δ(dI/dV)B = (dI/dV)B − (dI/dV)0 T for I⊥B (m) and for I‖B (n).
