- All-optical control of antiferromagnetic domains via an inverse optical magnetoelectric effect (2026) · Nature Materials · doi
The focus of spintronics has shifted from ferromagnets to antiferromagnets due to their faster spin dynamics and immunity to stray fields. Prior work has focused on ferromagnets, but there is a need to explore the all-optical control of antiferromagnetic domains.

The state-of-art antiferromagnetic switching mechanisms have long been limited for 90° or 120° switching of Néel vector. The paper identifies the need for a deterministic switching mechanism based on spin-orbit torque with asymmetric energy barrier.

The manipulation of antiferromagnetic order is a key requirement for antiferromagnet-based technologies, but the underlying mechanisms are not well understood. Prior work has demonstrated the potential of antiferromagnets for fast and energy-efficient device operations, but the switching dynamics of spin systems driven by spin-orbit torque in noncollinear antiferromagnets are not well studied.

The authors face the challenge of understanding the underlying mechanisms of multi-rotational switching. The authors must overcome the difficulty of fabricating and characterizing noncollinear antiferromagnetic nanodots. The authors need to develop a theoretical framework to explain the observed phenomena.
