Relativistic Néel-Order Fields Induced by Electrical Current in Antiferromagnets
Relativistic Néel-Order Fields Induced by Electrical Current in Antiferromagnets
We predict that a lateral electrical current in antiferromagnets can induce non-equilibrium N\'eel order fields, i.e. fields whose sign alternates between the spin sublattices, which can trigger ultra-fast spin-axis reorientation. Based on microscopic transport theory calculations we identify staggered current-induced fields analogous to the intra-band and to the intrinsic inter-band …
