18. In fact, in this region we find magnetic polytypism with two C-type phases: one with the crystallographic c axis and one with a doubled c axis. It is likely that this polytypism arises because of the weak magnetic coupling between the bilayers.
19. Photoemission measurements [e.g., D. Dessau, et al., Phys. Rev. Lett. 81, 192 (1998)] on x = 0.4 samples indicate that these orbitals are nearly degenerate, implying that a shift of electron density between the orbital manifolds may not be energetically costly.
