Fig. 1: Structural and magnetic surface symmetry.
From: Anisotropic atom motion on a row-wise antiferromagnetic surface
a Quasi-isotropic diffusion of an adatom on a hexagonal surface with six structurally equivalent directions. b Fcc(110) surface with typically preferred diffusion along close-packed atomic rows3,17. c Adatom on a row-wise antiferromagnet, with the ↑↑-rows breaking the hexagonal surface symmetry. Its magnetic moment is assumed to be parallel to the majority of neighboring Mn surface atoms.
