Spin-transport, spin-torque and memory in antiferromagnetic devices: Part of a collection of reviews on antiferromagnetic spintronics [PDF]
arXiv, 2017 Ferromagnets are key materials for sensing and memory applications. In contrast, antiferromagnets that represent the more common form of magnetically ordered materials, have so far found less practical application beyond their use for establishing reference magnetic orientations via exchange bias.

Fast domain wall motion induced by antiferromagnetic spin dynamics at the angular momentum compensation temperature of ferrimagnets [PDF]
, 2017 Antiferromagnetic spintronics is an emerging research field which aims to utilize antiferromagnets as core elements in spintronic devices. A central motivation toward this direction is that antiferromagnetic spin dynamics is expected to be much faster than ferromagnetic counterpart because antiferromagnets have higher resonance frequencies than ...

Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet
Advanced Materials, EarlyView.Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.

Group-Theoretical Analysis of Second Harmonic Generation at (110) and (111) Surfaces of Antiferromagnets [PDF]
, 1999 Extending our previous work we classify the nonlinear magneto-optical response at low index surfaces of fcc antiferromagnets, such as NiO. Antiferromagnetic bilayers are discussed here as models for the termination of bulk antiferromagnets.

Current Control of Spin Helicity and Nonreciprocal Charge Transport in a Multiferroic Conductor
Advanced Materials, EarlyView.A conducting multiferroic state of spin origin with both electronic polarity (P) and magnetization (M) can be controlled and detected by electric current in a high‐temperature helimagnet YMn6Sn6. The underlying concept is the coupling of the electric current with the toroidal moment T∼P×M$\bm{T}\sim \bm{P}\ensuremath{\times{}}\bm{M}$.

Part of a collection of reviews on antiferromagnetic spintronics. Antiferromagnetic dynamics, spin-texures, and nanostructures [PDF]
arXiv, 2017 Antiferromagnets as active elements of spintronics can be faster than their ferromagnetic counterparts and more robust to magnetic noise. Owing to the strongly exchange-coupled magnetic sublattice structure, antiferromagnetic order parameter dynamics are qualitatively different and thus capable of engendering novel device functionalities.

Proposing Altermagnetic‐Ferroelectric Type‐III Multiferroics with Robust Magnetoelectric Coupling
Advanced Materials, EarlyView.Multiferroics are highly sought after for advanced technological applications. Here, a novel class of type‐III multiferroics is proposed, where ferroelectricity and altermagnetism are inherently interlocked by crystal symmetry, setting them apart from conventional multiferroics. The ferroelectric switching is shown to fully invert the spin polarization
