    • Generally the determination of Ain is quite involved and is geometry dependent. For an order of magnitude estimate we consider the contribution from the local magnetic moments, Ref.. The z component of the resulting H field reads Hz (r) = 1 4π d r′ ρm (r′) (z- z′) | r- r′ | 3 H0 cosqx, H0 =- 1 4π d r′ z′ ρm (r′) | r′ | 3, ρm (r) =- Min (r), where Min is the oxide local magnetization, Min = (-1) n M0 nr. We thus have Bz (r) = μ0 [Hz (r) + Mz (r)] = B0 cosqx. In the Landau gauge the vector potential is space periodic, i.e., Ain = B0 (0, sinqx q, 0). Ain induces a periodic potential along the xi direction with an amplitude e B0 a2 q̄ (a is the lattice constant), which is tiny in our case (the local magnetic moment is 4 μB on each Mn site in R MnO3, Ref., the magnetic field is estimated as B0 ∼0.3T). The energy associated with the generated harmonic potential is e |Bz|/m=|Bz| me m × 10-1 meV with me being the free-electron mass. The effective mass m for the 2DEG at the oxide interfaces is me /m∼1/10, meaning a small energy contribution from the vector potential.
