Magnitudes of the Fe-Fe DM vectors for PdFe/Ir(111) as a function of the interatomic distance measured in units of the in-plane lattice constant (a2D) for different Fe layer relaxations. The inset shows a sketch of the in-plane components of the calculated DM vectors between a central Fe atom (C) and its nearest and next nearest Fe neighbors at −5% relaxation
