Fig. 2: Tabulation showcasing the isotropic, chiral and anisotropic contributions to the non-collinearity induced charge.

The arrows indicate the type of magnetic states that can be distinguished by the different terms. For example, the isotropic (a) induced charge differentiates the ferromagnetic and antiferromagnetic configurations. The chiral (b) term monitors the change of chirality, while the anisotropic (c) one senses the rotation of both moments with respect to the SOC anisotropy field. Here ei and ej are the unit vectors of two neighbouring magnetic moments, nji is the anisotropy field induced by SOC and φR stands for the Rashba-angle.
