    • Easy axes aligned at an angle to high-symmetry axes were reported previously for d-metal thin films [K. Baberschke and M. Farle, J. Appl. Phys. 81, 5038 (1997)] and some 4f bulk materials [M. Colarieti-Tosti et al., Phys. Rev. Lett. 91, 157201 (2003)], and were explained by a competition of second and fourth order MAE constants. This form of MAE is different from that of the Co-wire easy axis as it does not require symmetry breaking.

    • z=0 was adopted in order to simulate the 2D character of the problem, notwithstanding that the supercell calculations themselves are inherently three dimensional.
