33. Local magnetic fields from a ferromagnet may lead to suppression of superconductivity near the interface [e.g., Y. Miyoshi, Y. Bugoslavsky, and L. F. Cohen, cond-mat/0410264 (unpublished)]. This is possible if magnetic moment in (Ga,Mn)As has an out-of-plane component. However, due to a compressive strain, magnetization in 8% Mn(Ga,Mn)As epilayers is in plane.

35. Another possible mechanism of inelastic scattering is due to magnons, see G. Tkachov, E. McCann, and V. I. Fal'ko, Phys. Rev. B PRBMDO 0163-1829 10.1103/PhysRevB.65.024519 65, 024519 (2001). This, however, should lead to a significant asymmetry of the I - V characteristics, which has not been observed.
