From: Electrically induced and detected Néel vector reversal in a collinear antiferromagnet
Microscopic mechanism of the second-order magnetoresistance. a Probing current (black arrow) generates staggered non-equilibrium spin polarization (red and purple electron symbols with arrows) that causes transient deflection of the antiferromagnetic moments (thick red and purple arrows on Mn sites). b The 180° reversal of the Néel order probed by the current-dependent resistance δRxx, associated with the electrically induced deflection of antiferromagnetic moments (double-arrows) combined with AMR, for equilibrium antiferromagnetic moments (semi-transparent double-arrows) aligned at an angle 45° from x axis of the probing current. c Same as b for δRxy and equilibrium antiferromagnetic moments aligned with x axis
