Spin-split antiferromagnets have significance for antiferromagnetic (AFM) spintronics due to their momentum dependent spin polarization which can be exploited for the control and detection of the AFM order parameter. While many 3D antiferromagnets exhibiting non-relativistic spin splitting (NRSS) in their electronic band structure have been proposed and demonstrated, such property remains...
Contrary to the early understanding of antiferromagnets as limited compared to ferromagnets, a rich landscape of phenomena in antiferromagnets has been demonstrated that could be utilized for various spintronics functionalities. Here, we discuss recent advances in understanding of how electrical current can induce spin currents or spin torques in antiferromagnetic systems, focusing primarily...
We present a systematic classification of the magnetic ground states in hundreds of two-dimensional (2D) materials. Non-collinear order is shown to be abundant and may typically be represented by planar spin spiral ground states. We discuss a range of physical effects associated with non-collinear order and take specific materials as examples. The Ni(Cl,Br,I)$_2$ compounds exhibit type II...
Magnetoelectricity, accounting for the coupling between electric and magnetic dipoles, has attracted a revived interest in the last few decades. The interest was largely fueled by the renaissance of multiferroicity where coexisting electrical and magnetic degrees of freedom may couple, as indeed happens in type-II multiferroics displaying an electric polarization induced by a symmetry-breaking...
Magnetization in solids arises from both orbital and spin degrees of freedom. While spin-related effects, such as the spin Hall and inverse spin Hall effects, have been widely considered the dominant mechanisms in magnetoelectric phenomena, recent experimental evidence suggests a much more significant role for orbital contributions than previously expected. This has led to the development of...
The spin-orbit torque (SOT) mechanism offers new avenues for magnetic technologies, where spin-orbit coupling (SOC) at a metal-magnet interface is harnessed to electrically manipulate the magnetic state. Van der Waals materials emerge as a natural SOT platform due to their layered structure, where furthermore SOC and magnetic properties can be tailored by proximity effects. However, low SOT...
