Schematic representation of a triangular trimer of: (a) Cr on Au(111), (b) Mn on Au(111) fcc and (c) Mn on Ag(111) fcc surfaces. The dark red arrows denote the DMI directions (\(\mathbf {D}_{ij}\)), in case of NC magnetic configuration (Néel type state), and they are positioned in-between two atoms which the interaction corresponds to. (d) Diagram with the different magnetic configurations used in the DMI calculations as a function of the \(\theta\) and \(\alpha\) angles.
