 The recently proposed coupling between the angular momentum density and magnetic
moments is shown to provide a straightforward alternative explanation for galvanomagnetic
effects, i.e. for both anisotropic magnetoresistance (AMR) and planar Hall effect (PHE). Such
coupling naturally reproduces the general formula associated with AMR and PHE and allows
for the occurrence of so-called ‘negative AMR’. This coupling also provides a unifying link
between AMR, PHE and the anomalous Hall effect (AHE) since this same coupling was
previously found to give rise to AHE (Bellaiche et al  2013 Phys. Rev.  B 88 161102 ).
