17. With carrier density of n∼2×1028/m3 (C.H. Ahn et al., submitted), and assuming a single quasiparticle scattering time τ, the value of (ωcτ)2 which is expected to be proportional to the orbital MR, Δρ/ρ(0), is ∼10−3(B/ρ(0))2 (ωc is the cyclotron frequency, ρ is the resistivity in μΩcm, and B is the field in tesla). Thus even with residual resistivity of 7μΩcm (for our best film), we do not expect significant MR at any temperature. In addition, the strong temperature dependence of the anisotropic MR near Tc together with the scaling of the MR give further evidence that the MR is related to M and not B.
18. In fact, the magnetocrystalline anisotropy prevents full orientation of M along H at low temperatures. Therefore, the measured AMR of ∼20% is only a lower bound.

23. Although the imaging was done at T∼100K, the domain wall structure remained unchanged starting from a few degrees below Tc and lower; therefore, we expect the same structure at 5K.
