Fig. 1: Principle of magnonic charge current generation in Mn2Au.
From: Antiferromagnetic magnonic charge current generation via ultrafast optical excitation
a The crystalline structure of Mn2Au. Magnetic sublattices MnA and MnB are marked in red and green, respectively. b The orientation fluctuation, and magnitude reduction of the local magnetic moments in Mn2Au is triggered by the femtosecond laser pulse, which results in a non-equilibrium spin polarization with the opposite sign on the adjacent Mn sublattices. c Staggered spin polarization generated at magnetic sublattices, giving rise to the charge current by the reciprocal relationship of Néel spin-orbit torque (NSOT).
